What happened?

hi team,

i'm getting below error when try to unqoute the body.

 collector server run finished with error: failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:
error decoding 'receivers': error reading configuration for "filelog": 1 error(s) decoding:
error decoding 'operators[48]': unsupported type 'unquote'

if something which can't be done using unqoute operator , is there any other way around to unqoute and remove extra backslash from json logs?

the message in body as
"body": "{"SeverityText":"Information","Message":"Processing message"}\n"

i'm refering below doc to unqoute the body.

Could you try 0.85.0 version, pls?
I believe this MR fix the issue - #26453

hi @jangaraj .

is this correct way to unquote body ?

• type: remove
  field: body
  Ref from doc:

thanks.

@kadhamecha-conga, thanks for pointing out this typo. I've opened #27025 to address it.

I'll close this issue but please let us know if you are unable to use the operator on the latest version.
