Scripted Metric Aggregation fails on unexpected = character - elasticsearch

I'm trying to have some object containing all time deltas between two logs with the same recordId.
In order to do so, I'm executing the following query (Scripted Metric Aggregation) on elastic search, where the logs are, using fiddler:
{
"query": {
"exists": {
"field": "recordId"
}
},
"aggs": {
"deltas": {
"scripted_metric": {
"init_script": {
"source": "state.deltas = {};",
"lang": "expression"
},
"map_script": {
"source": " if (!(doc['topic'].value in state.deltas)) { state.deltas[doc['topic'].value] = {} } state.deltas[doc['topic'].value][doc['recordId'].value] = !(doc['recordId'].value in state.deltas[doc['topic'].value]) ? doc['#timestamp'].date.millisOfDay : Math.abs(state.deltas[doc['topic'].value][doc['recordId'].value] - doc['#timestamp'].date.millisOfDay) ",
"lang": "expression"
},
"reduce_script": {
"source": " res = {}; for (s in states) { for(topic in Object.keys(s.deltas)) { if (!(topic in res)) { res[topic] = {} } for(recordId in Object.keys(s.deltas[topic])) { res[topic][recordId] = !(recordId in res[topic]) ? s.deltas[topic][recordId] : Math.abs(res[topic][recordId] - s.deltas[topic][recordId]) } } } return res;",
"lang": "expression"
}
}
}
}
}
But it fails because of unexpected '=' character...
Tried other ways but it always throws the same error.
What am I missing?

Elasticsearch Scripted metric- list to map

I have a document in sub aggregation in this format -
{
"tradeDateTime": "2022-07-11T13:07:00.000Z",
"status_count": 2,
"executingEntityIdCode": "635400BDQCJNMOGTBB61",
"status": {
"NEW": {
"tm": {
"submissionAccountName.keyword": "ACCOUNT1",
"assetClass.keyword": "EQUI",
"regulator.keyword": "BaFIN",
"status.keyword": "NEW"
}
},
"NEW-2": {
"tm": {
"submissionAccountName.keyword": "ACCOUNT1",
"assetClass.keyword": "BOND",
"regulator.keyword": "BaFIN",
"status.keyword": "NEW-2"
}
}
}
}
I need to get values from status in a map that can give me a count of unique status values. for example in this case -
NEW: 1
NEW-2 : 1
basically traverse the list and reduce it to a map.
"aggs": {
"topmostAggregation": {
"scripted_metric": {
"init_script": "state.final = []",
"map_script": "state.final.add(doc.status.value)",
"combine_script" : "Map myMap = [:]; for(t in state.final){ myMap.put(t.value,t.value) } return myMap; ",
"reduce_script" : """
return myMap;
"""
},
I am not sure how do I get value of tag inside status. This script gives me an error

Is there any problem in my elasticsearch request?

I'm trying to update a doc in elasticsearch by using:
POST /rcqmkg_eco_ugc_rec/_doc/aaa/_update
{
"script": {
"source": "ctx._source.flower_cnt_0 += params.flower_cnt_0",
"lang": "painless",
"params": {
"flower_cnt_0": 1
}
}
}
But I got a illegal_argument_exception error. The result of elasticsearch is:
{
"error": {
"root_cause": [
{
"type": "remote_transport_exception",
"reason": "[data1_xxx][xxx][indices:data/write/update[s]]"
}
],
"type": "illegal_argument_exception",
"reason": "failed to execute script",
"caused_by": {
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.flower_cnt_0 += params.flower_cnt_0",
" ^---- HERE"
],
"script": "ctx._source.flower_cnt_0 += params.flower_cnt_0",
"lang": "painless",
"caused_by": {
"type": "null_pointer_exception",
"reason": null
}
}
},
"status": 400
}
Where is the problem in my update request of es?
If the document you're trying to update might not contain a field called flower_cnt_0, you need to account for this in your script:
Try this instead:
POST /rcqmkg_eco_ugc_rec/_doc/aaa/_update
{
"script": {
"source": "ctx._source.flower_cnt_0 = (ctx._source.flower_cnt_0 ?: 0) + params.flower_cnt_0",
"lang": "painless",
"params": {
"flower_cnt_0": 1
}
}
}

How to update and strip the first character of an array field in elasticsearch

I have the following within an index in elastic search listed as a json doc
Current
{
"bar": {
"bar": [{
"bar": [{
"bar": [{
"foo": "Y111111111111"
}
]
}
]
}
}
}
Update needed
{
"bar": {
"bar": [{
"bar": [{
"bar": [{
"foo": "111111111111"
}
]
}
]
}
}
}
How would I go about updating the index to strip the first character of the string where equal to bar?
I tried the following syntax which works for a single field but I receive an exception when running on an array field
{
"error": {
"root_cause": [
{
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.foo = ctx._source.foo.substring(1);",
" ^---- HERE"
],
"script": "ctx._source.foo = ctx._source.foo.substring(1);",
"lang": "painless"
}
],
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.foo = ctx._source.foo.substring(1);",
" ^---- HERE"
],
"script": "ctx._source.foo = ctx._source.foo.substring(1);",
"lang": "painless",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "Illegal list shortcut value [foo]."
}
},
"status": 400
}
POST test/_update_by_query
{
"query": {
"prefix": {
"foo": "Y"
}
},
"script": {
"source": "ctx._source.foo = ctx._source.foo.substring(1);"
}
Mapping
{
"TEST": {
"mappings": {
"properties": {
"bar": {
"properties": {
"bar": {
"properties": {
"bar: {
"properties": {
"bar": {
"properties": {
"foo": {
"type": "keyword"
}
}
}
}
}
}
}
}
}
}
}
}
}
I would do it as follows. Find all documents whose foo field starts with Y and then update all the foo fields by stripping the first character:
POST test/_update_by_query
{
"query": {
"prefix": {
"bar.bar.bar.bar.foo": "Y"
}
},
"script": {
"source": "ctx._source.bar.bar[0].bar[0].bar[0].foo = ctx._source.bar.bar[0].bar[0].bar[0].foo.substring(1);"
}
}
PS: the query will depend on whether your bar fields are nested or not, but in case they are not, the above query should work.

Update nested string field

I am trying to update a field image.uri by _update_by_query:
POST user/_update_by_query
{
"script": {
"source": "ctx._source.image.uri = 'https://example.com/default/image/profile.jpg'",
"lang": "painless"
},
"query": {
"bool": {
"must_not": [
{
"exists": {
"field": "image.id"
}
}
]
}
}
}
But it throws error:
{
"error": {
"root_cause": [
{
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.image.uri = 'https://example.com/default/image/profile.jpg'",
" ^---- HERE"
],
"script": "ctx._source.image.uri = 'https://example.com/default/image/profile.jpg'",
"lang": "painless"
}
],
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.image.uri = 'https://example.com/default/image/profile.jpg'",
" ^---- HERE"
],
"script": "ctx._source.image.uri = 'https://example.com/default/image/profile.jpg'",
"lang": "painless",
"caused_by": {
"type": "null_pointer_exception",
"reason": null
}
},
"status": 500
}
A sample document:
{
"image": {
"uri": "https://example.com/resources/uploads/default_files/profile/thumb/large/default_profile.jpg"
},
"created": "2018-06-06T21:49:26Z",
"uid": 1,
"name": "Jason Cameron",
"username": "jason"
}
UPDATED RESPONE
The problem could be coming from a document without image object in it.
Try to add strict mapping if possible, to avoid indexing documents without image object.
OLD RESPONSE/"\' are correct for use inside painless script as string
Your problem comes as use of ' to encapsulate your uri, strings must be encapsulated by ".
Try to modify your script as:
"script": {
"source": "ctx._source.image.uri = \"https://example.com/default/image/profile.jpg\"",
"lang": "painless"
}

NPE when partially updating Elasticsearch Index

I'm following the example over here for updating a set of tags using the partial update in Elasticsearch.
Following is my script:
{
"script": {
"lang": "painless",
"inline": "ctx._source.deviceTags.add(params.tags)",
"params": {
"tags": "search"
}
}
}
Request URL is:
https://aws-es-service-url/devices/device/123/_update
But I'm getting the following response:
{
"error": {
"root_cause": [
{
"type": "remote_transport_exception",
"reason": "[fBaExM8][x.x.x.x:9300][indices:data/write/update[s]]"
}
],
"type": "illegal_argument_exception",
"reason": "failed to execute script",
"caused_by": {
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.deviceTags.add(params.tags)",
" ^---- HERE"
],
"script": "ctx._source.deviceTags.add(params.tags)",
"lang": "painless",
"caused_by": {
"type": "null_pointer_exception",
"reason": null
}
}
},
"status": 400
}
Any idea of what I have done wrong?
Since your deviceTags array is initially null, you have two ways to solve this
A. Use upsert to make sure that deviceTags gets added to your document initially
{
"script": {
"lang": "painless",
"inline": "ctx._source.deviceTags.add(params.tags)",
"params": {
"tags": "search"
}
},
"upsert": {
"deviceTags": ["search"]
}
}
B. Protect your code against NPE
{
"script": {
"lang": "painless",
"inline": "(ctx._source.deviceTags = ctx._source.deviceTags ?: []).add(params.tags)",
"params": {
"tags": "search"
}
}
}
