Can I delete the body of a log using the transformprocessor or any other processors?

[azagarelz]

I'm trying with no luck to delete the Body using the transformprocessor.
I tried:

          - context: log
            statements:
              - set(log.body, nil)

          - context: log
            statements:
              - delete_key(log, "body")

But nothing seems to work.

Am I missing an obvious way to do that?

Hi @azagarelz, the set function currently does not allow setting nil values, that's why your statement is not changing the log data.

value is any value type. If value resolves to nil, e.g. it references an unset map value, there will be no action.

As an alternative, you can set it to empty string (or any other supported type):

 - context: log
   statements:
    - set(body, "")

Resulting in something like:

"body": {
 "stringValue": ""
}

Instead of empty when nil:

"body": {}

You can test that out here, if that does not work for you, I suggest you to open an issue to further discuss it. Thanks!

Thanks a lot!
Using an empty string worked for my use case.
