Script not executing _update_by_query

Elastic Stack Elasticsearch
1

Hi,

I am trying to update several documents at the same time using the update
by query plugin.

The problem seems to be with the script as the query it self returns the
correct result with no issues. The thing is ES seems to be able to execute
the script as there are no exceptions in the logs. Yet nothing gets updated.

So here is the document I am indexing:

curl -XPUT 'localhost:9200/users/files/1' -d '
{
"path" : "path/to/file"
"size": 200
}'

No here is my update by query request to change the path field from
'path/to/file' to 'another/path/to/file':

curl -XPOST 'localhost:9200/users/files/_update_by_query' -d '
{
"query": {
"bool": {
"must": [
{
"term": {
"path": "path/to/file"
}
}]
}
},
"script": "def str = ctx_source.path;\ndef str2 =
str.replaceAll("path/to/file",
"another/path/to/file");\nctx._source.path = str2;"
}'

And this is what I get:
{
"ok":true,
"took":516,
"total":75,
"updated":0,
"indices":[
{
"new_index":{}
}]
}

so the query matched 75 documents but did not update any.
Anyone knows how can I make it work.

**Here is the script in pretty form:

def str = ctx_source.path;
def str2 = str.replaceAll("path/to/file", "another/path/to/file");
ctx._source.path = str2;

NVM, found the culprit.

Was missing a '.':

def str = ctx_source.path; -> def str = ctx*.*_source.path;

Weird how there was nothing in the logs about this

+1. If you can make it reproduceable in a readable gist I'd file it as an
issue. Groovy should be complaining about ctx_source not being in scope.

Sorry for the delay was a bit occupied making sure everything worked as
expected.

So here, I created a gist of the issue and hope it proves useful:

Yup - still looks like a bug to me. I think the right thing to do is file
it on github.
