ottlfunc regex doesn't support double quotes about opentelemetry-collector-contrib HOT 5 OPEN

The code owners for pkg/ottl will have better insight than me here, but at a glance, the regex and replacement arguments in the replace_pattern function call need to be enclosed in double quotes as they're strings.

The following works for me:

- replace_pattern(attributes["Body"], "(?U)name\":\"(.*)\"", "name\":\"**********\"")

(?U)name\":\"(.*)\", name\":\"**********\", should become "(?U)name\":\"(.*)\", name\":\"**********\","

Doing so, the Collector fails with error:

You'll need to escape * as well: replace_pattern(attributes["Body"], "(?U)name\":\"(.*)\", name\":\"\*\*\*\*\*\*\*\*\*\*\",").

I suggest testing that your regex is well formatted and then adding it to your config.
