Trying to understand why replace isn't working on a regex

[calebcall]

I have this example logs message/event:

{"file":"/var/lib/service/nodes/406a6907-6133-48d4-85f6-cc5122bdcc65/data/protocol_data/worker/worker.log","hostname":"node.example.com","message":"\u001b[2m2025-06-02T03:45:06.475906Z\u001b[0m \u001b[32m INFO\u001b[0m \u001b[2mworker::controller::p2p\u001b[0m\u001b[2m:\u001b[0m Sending 1 logs (606 bytes)","source_type":"file","timestamp":"2025-06-02T15:12:43.709155183Z"}

I'm trying to remove the ANSI color coding that's coming through the logs.

I'm trying with this replace function replace(string!(.message), r'\\u001b\[[0-9]*[mK]', "")

No errors, but no replacement is happening. The regex correctly matches according to regex101 testing. I must be doing something wrong with the replace functionality.

This might be due to #148 (lack of unicode escapes working in literals).

Definitely seems related. I found that this from that issue works!
