Start with regex: '(.*)'
If that works, then you know it's just the regex at fault. I'd start by
trying to double-backslash, i.e.
- regex: '([\\w]{2}:[\\w]{2}:[\\w]{2}:[\\w]{2}:[\\w]{2}:[\\w]{2})'
The spec for Go's regex language (RE2) is
here: https://github.com/google/re2/wiki/syntax
I'm not sure if a backslash character class is allowed inside a
square-bracket character class. So you could try:
- regex: '((\\w){2}:(\\w){2}:(\\w){2}:(\\w){2}:(\\w){2}:(\\w){2})'
- regex:
'([[:alnum:]]{2}:[[:alnum:]]{2}:[[:alnum:]]{2}:[[:alnum:]]{2}:[[:alnum:]]{2}:[[:alnum:]]{2})'
or something simpler like:
- regex: '([a-fA-F0-9:]{17})'
