             Summary: Prometheus plugin crashes Asterisk when using local channel
                 Key: ASTERISK-30239
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30239
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_local
    Affects Versions: 19.6.0
         Environment: default Debian / Ubuntu no fancy stuff
            Reporter: Joeran Vinzens
            Severity: Major


We use ARI to create Channels. There are local Channels.
The Asterisk crashes if there are local channel and if queried by 

When we reproduce it it crashes ever time at the same spot.

1. we produce an incoming Channel by placing a call from a softphone
2. we create an local channel using ARI
if we now query /metrics provided by res_prometheus asterisk will crash

Attached is a bundle of configs and a shell script where you can see what is going on. (it is dirty just to reproduce the issue)

the script is ment to create a local channel, two bridges and put the incoming channel into first bridge, local channel in both bridges and than create an outgoing PJSIP Channel and place this one into the the bridge, the incoming channel is not in. So at the end we would have incoming Call -> Bridge -> local Channel -> Bridge -> outgoing Channel

Attached is the Script
extensions.conf
pjsip.conf
