Problem

I have encountered an issue with parsing json strings with single quotes:
the following VRL expression:

.bad = parse_json!(.bad)

parsing the following event:

{
    bad: "{'test': 'hello'}"
}

returns an error saying the json is invalid...

I also tested in the VRL playground
Please help :)
Thanks in advance
