I've been having a problem lately where I can't access the value of any variable through their name. It's not a connection problem since I can read the value from the read() function just fine. However whenever I use the read_by_name function there's always the same error pyads.pyads_ex.ADSError: ADSError: Unknown Error (857212673).
Because it's an unknown error I haven't been able to find documentation on it. I'm using a BC9120 as a PLC and TwinCat 2. Does anyone know what might be causing this?
Code:
if self.plc.is_open == False:
self.plc.open()
print(self.plc.read(pyads.INDEXGROUP_MEMORYBIT, 0*8 + 0, pyads.PLCTYPE_BOOL))
print(self.plc.read_by_name("Test.M0", pyads.PLCTYPE_BOOL))
Logs:
False

I try to use Lambda function splunk-firehose-flowlogs-processor to transform data from vpc flowlogs before sending them to splunk. I do it according to amazon blogpost: https://aws.amazon.com/blogs/big-data/ingest-vpc-flow-logs-into-splunk-using-amazon-kinesis-data-firehose/
I used test data and it worked but suddenly I started to get an Lambda function error:
[ERROR] KeyError: 'message'
Traceback (most recent call last):
File "/var/task/app.py", line 127, in lambda_handler
records = list(processRecords(event['records']))
File "/var/task/app.py", line 74, in processRecords
joinedData = ''.join(transformLogEvent(data))
File "/var/task/app.py", line 66, in transformLogEvent
return log_event['message'] + '\n'
I'm really confused and I think maybe there is someone who knows why this Lambda function gives errors.
It's very often for me to get error when trying to stop or start ec2-instances through AWS Lambda. Quite strange for me, because sometimes it works (for both start and stop ec2-instances).
The error I get is like below. When I run test on Lambda console, most of the time it successfully executed. But when I run it through AWS Event Rules (CloudWatch), it's very often the function got fail.
This is my code on line 48

This is my code for start & stop the instances:
Even, I already move instantiation og ec2_res ec2_client inside the function but it did not help.,
def start_ec2_instances():
try:
ec2_res = boto3.resource('ec2', region_name="ap-southeast-2")
ec2_client = boto3.client('ec2', region_name="ap-southeast-2")
ec2_client.start_instances(InstanceIds=ec2_instances)
for ec2_id in ec2_instances:
instance = ec2_res.Instance(id=ec2_id)
logger.info("Waiting instance " + ec2_id + " to start")
instance.wait_until_running()
return True
except bex.ClientError as err:
logger.error(err.response['Error']['Message'])
return False
def stop_ec2_instances():
try:
ec2_res = boto3.resource('ec2', region_name="ap-southeast-2")
ec2_client = boto3.client('ec2', region_name="ap-southeast-2")
ec2_client.stop_instances(InstanceIds=ec2_instances)
for ec2_id in ec2_instances:
instance = ec2_res.Instance(id=ec2_id)
logger.info("Waiting instance " + ec2_id + " to stop")
instance.wait_until_stopped()
return True
except bex.ClientError as err:
logger.error(err.response['Error']['Message'])
return False
If any one of you ever face the same guys?
Thanks
Edit: I set function timeout to 8 minutes. In normal condition, time required to execute the function is less than 5 minutes.
Additional note:
Sometimes I work using VPN (south-east-2) in which this VPN is in a different region from the region I live. Instances (and another components) also deployed on this region VPN (south-east-2).
Your code to start and stop the instance looks right to me. The timeout is happening because the time taken to perform your operation is not getting completed in the configured timeout for your lambda function.
You can measure what is the time taken for your function by simply subtracting the time between start and stop of the function.
The default timeout is 3 seconds. So you should consider increasing this timeout interval for your lambda function. Say to 5 minutes.
Please note that the maximum value for this timeout is 300 seconds(15 minutes) and you can not configure value higher than this. I am sure the above code would complete within that limit and hence it should not be a problem for you.
How do I increase my timeout interval for my lambda function?
There are multiple ways to do this. By AWS CLI, AWS console, or probably some other way.
In AWS Console you can do like this:
Click on the Save button after doing this change.
Hope this helps.
There was no problem with this code. But one day, suddenly, an error started to appear. Please help me. (I used the translator.) Thanks
I have no idea.. Sorry.

Have a look here: https://discordpy.readthedocs.io/en/latest/api.html?highlight=create_voice#discord.Guild.create_voice_channel
You must use
await ctx.guild.create_voice_channel(**kwargs)
Instead of your code. Next times better if you give the docs a look before asking here.
I'm working on a Window 10 machine and trying to pip install mlflow but I'm getting the following error message.

What's this issue?
This seems due to some bad network setup issues - as you can observe from the fact that you have a socket timeout on what appears to be a pip install.
I'm trying to use a parameter expression in the plone.app.theming theming-controlpanel that gets a value from the portal_registry to use within the rules.xml file of the theme.
The goal is that if a boolean is set in the registry, the theme can allow/disallow certain content.
So my parameter expression (in theming-controlpanel) is
enable_ad_tags = python:context.portal_registry['lw.portal.enableadtags']
There is a corresponding boolean field in the portal_registry.
The rules.xml file has this rule:
<!-- Global Ad Tags -->
<drop css:theme="#globalAdTags" if="not($enable_ad_tags)" />
The problem is that on my local machine i get this error in the console all the time:

Is there a problem with the pattern I am trying to use here?
Is there a better/safer way to achieve this?
Using portal instead of context works:
enable_ad_tags = python:portal.portal_registry['lw.portal.enableadtags']
IMHO context should also work, or context does not behave like it does, or the naming is wrong.
