I am trying to convert the hex value (coming as part of content of the flowfile) 2c0f19d10da4e92896faf7a92ce26f94d2fe91acdc2a69730731613f7c094a36 using fromRadix() EL in UpdateRecord processor. Below is the code I have used
${field.value:isEmpty():not():ifElse('${field.value:fromRadix(16)}','${literal("")}')}
But am getting error, "will route to failure: For input String "2c0f19d10da4e92896faf7a92ce26f94d2fe91acdc2a69730731613f7c094a36"
I tried it through Groovy with the below code, it is working fine.
def data1 = '2c0f19d10da4e92896faf7a92ce26f94d2fe91acdc2a69730731613f7c094a36'
BigInteger x = new BigInteger(data1,16)
println "original output: " + x
Output is coming as
original output: 19928446223359820201840237302010524452213876686816802601399388669528806869558
Would like to know what is wrong with my UpdateRecord processor code using fromRadix(16)
I ran into something very similar, it seems like the NiFi expression language throws an error when the input value (hex in this case) is a big string.
Instead of this "2c0f19d10da4e92896faf7a92ce26f94d2fe91acdc2a69730731613f7c094a36" try running it for "2c0f19d10da" (subtring of your input) and it works.

Below is the JSON Response from the Server, How to remove the characters �� from the below Response using Jmeter
Response :
{"_id":"5d56cc5c31acfd001298e863","test_id":"5d56cc593801370012bdb2bb","display_order":"1","question_type":"MULTIPLE CHOICE","isbn":"9780393630749","status":"added","question":{"_id":"5d56cc5c31acfd001298e864","questionId":"5d4262bb56c1d800122fcb48","QuestionTitle":{"key":"","value":"","valueRTF":"","valueHtml":"��������\n
I have written the groovy Script. but it is not removing the char.
def response = prev.getResponseDataAsString();
def var1= response.replaceAll("\�", "");
and I need to use this Var1 in another request.
Most probably you're seeing these question marks due to encoding problems, try setting file.encoding property to UTF-8 in system.properties file and restart JMeter, most probably you will see normal text instead of the question marks.
If for some reason the above hint is not applicable I would recommend replacing the whole valueHtml attribute value using JsonBuilder, the relevant code would be something like:
def builder = new groovy.json.JsonBuilder(new groovy.json.JsonSlurper().parse(prev.getResponseData()))
builder.content.question.QuestionTitle.valueHtml = ''
vars.put('Var1', builder.toPrettyString())
As the result you will have the same JSON structure with empty valueHtml attribute.

Apache Groovy - Why and How You Should Use It
As it is a JSON Response, add JSON Extractor Post Processor to the Parent Sampler from where the Response is expected. Extract whole JSON with following settings:
Now, use a JSR223 Sampler, with following code in script area:
String var1 = vars.get("jsonOutput");
log.info("Output: " + var1);
String replaceString=var1.replace('?','-'); // replace with whatever you want to, I am replacing it with '-'
log.info("Output: " + replaceString);
vars.put("NewString", replaceString);
Afterwards, you can use ${NewString} wherever you want.
I am trying to use file name path (Ex: C:\Document\Report.txt) as a parameter through uipath orchastrator api. I tried different approach and In each approach I am getting Bad request error "{"message":"Argument Values validation failed.","errorCode":2003,"resourceIds":null}"
Below is my Example code
FileListUploaded ="C\\Documents\\report.txt";
string parameter1 = "{\"startInfo\": {\"ReleaseKey\": \"xxxxx-xxx-xxx-xxx-xxxxxx\"," +
"\"RobotIds\": [xxxxx]," +
"\"JobsCount\": 0," +
"\"InputArguments\": \"{ "+
"\\\"reports_or_other_files\\\": \\\" + FileListUploaded + \\\"}\"}}";
request_startRobot.AddParameter("application/json; charset=utf-16", parameter, ParameterType.RequestBody);
IRestResponse response_startRobot = client_startRobot.Execute(request_startRobot);
That's a bit messy to look at, but it appears you are not quoting and escaping your JSON correctly.
I might suggest building an array and serializing it into JSON to make it easier to read, or using a HEREDOC or string formatting. If you do continue to concatenate your JSON body string together, dump out the results to see how it is coming together.
The final results of the JSON should look something like
{
"startInfo": {
"ReleaseKey":"{{uipath_releaseKey}}",
"Strategy":"JobsCount",
"JobsCount":1,
"InputArguments":"{\"reports_or_other_files\":\"C:\\\\Documents\\\\report.txt\"}"
}
}
With the InputArguments:
Looks like you are missing some quotes
Might need to double escape your backslashes in the FileListUploaded variable
Missing a colon after the C in the path
I am trying to do the following:
String x=null;
Group group = factory.newGroup()
.append("x", x);
context.write(null,group)
With the following scheme:
String writeSchema = "message example {\n" +
"optional binary x;\n" +
"}";<br>
But I get NullPointerException in the append line. Maybe I am missing something in the scheme?
Here the String object itself is null. While writing to the filesystem it tries to get the value of the object which is causing the NullPointerExeception.
String x =null;
System.out.println(x.toString()); // Will cause a NullPointerExeception
Similarly any function call to the object will cause the same.
Try using String x ="null" instead
Given this ApiController:
public string TestString() {
return "The value is: " + 1.23;
}
public double TestDouble() {
return 1.23;
}
With the browser's language set to "fr-FR", the following happens:
/apiController/TestString yields
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">The value is: 1,23</string>
/apiController/TestDouble yields
<double xmlns="http://schemas.microsoft.com/2003/10/Serialization/">1.23</double>
I would expect TestDouble() to yield 1,23 in the XML. Can anyone explain why this isn't the case and, more importantly, how to make it so that it does?
It is because the conversion from double to string happens at different stage for each API. For the TestString API, double.ToString() is used to convert the number to a string using CurrentCulture of the current thread and it happens when the TestString method is called. Meanwhile, the double number which is returned by TestDouble is serialized to string during the serialization step which uses GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Culture.
In my opinion, both should use InvariantCulture. On the consumer side, the values will be parsed and be formatted with the correct culture.
Update: this is only used for JsonFormatter. XmlFormatter doesn't have such a setting.
Update 2:
It seems (decimal) numbers need special converter to make it culture-aware:

Btw, if you want o change data format per action/request, you can try the last piece of code of the following link: http://tostring.it/2012/07/18/customize-json-result-in-web-api/
When using the MongoDB shell, how do I use a guid datatype (which I have used as the _id in my collection).
The following format doesn't work:
>db.person.find({"_id","E3E45566-AFE4-A564-7876-AEFF6745FF"});
Thanks.
You can use easily:
.find({ "_id" : CSUUID("E3E45566-AFE4-A564-7876-AEFF6745FF")})
You have to compare the _id value against an instance of BinData (not against a string). Unfortunately the BinData constructor takes a Base64 string instead of a hex string.
Your GUID value is missing two hex digits at the end, so for the purposes of this example I will assume they are "00". The following values are equivalent:
hex: "E3E45566-AFE4-A564-7876-AEFF6745FF00" (ignoring dashes)
base64: "ZlXk4+SvZKV4dq7/Z0X/AA=="
So your query should be:
>db.person.find({_id : new BinData(3, "ZlXk4+SvZKV4dq7/Z0X/AA==")})
I am assuming that the binary subtype was correctly set to 3. If not, what driver was used to create the data?
You could use the following js function in front of your query like so:
function LUUID(uuid) {
var hex = uuid.replace(/[{}-]/g, ""); // removes extra characters
return new UUID(hex); //creates new UUID
}
db.person.find({"_id" : LUUID("E3E45566-AFE4-A564-7876-AEFF6745FF"});
You could save the function in .js file and load it or open it before you make your query and if you copy the value from your results you should rename the function with:
LUUID for Legacy UUID
JUUID for Java encoding
NUUID for .net encoding
CSUUID for c# encoding
PYUUID for python encoding
I know it's an old issue, but without any additional needs you can use this one:
find({_id:UUID('af64ab4f-1098-458a-a0a3-f0f6c93530b7')})
You can fix this issue by using split() and join() workaround:
for instance if I use "E3E45566-AFE4-A564-7876-AEFF6745FF" hex value with - inside UUID() function, it does not return BinData in mongo so please try removing all the - before passing to UUID function.
db.person.find({"_id":UUID("E3E45566-AFE4-A564-7876-AEFF6745FF".split("-").join(''))});
Or by defining a variable to do it in multiple line:
var uuid = UUID("E3E45566-AFE4-A564-7876-AEFF6745FF".split("-").join(''))
db.person.find({"_id":uuid});
or by creating a simple function:
function BUUID(uuid){
var str = uuid.split("-").join('');
return new UUID(str);
}
db.person.find({"_id": BUUID("E3E45566-AFE4-A564-7876-AEFF6745FF")}).pretty();
