regex producing invalid priority error

[perkons]

OpenBSD 6.8 Asterisk 18.1.1

asterisklint dialplan-check extensions.conf produces error:

extensions.conf:9 E_DP_PRIO_INVALID: invalid priority '3]XX'

Content of extensions.conf:

[general]
static=yes
writeprotect=yes
clearglobalvars=no

[globals]

[phones]
exten => _[2,3]XX,1,NoOp(Incoming call for ${EXTEN})

[wdoekes]

_[2,3]XX,1,NoOp(Incoming call for ${EXTEN})

It is not a regex, nor it is a glob-pattern. It's an asterisk-specific thing.

And AsteriskLint rightly complains. You should have _[23]XX

[perkons]

Yes, this is an old config on our Asterisk hosts. Just changed and tested it, it is working like this _[23]XX

Thanks for the fast answer!
