When trying to make calls to the ARI channels we were getting the error “allocation failed”. When looking at the asterisk logs we would see the following error
ast_json_vpack: Error building JSON from ‘{s: s?, s: s?, s: o, s: s?, s: s?}’: Expected format ‘s’, got ‘?’.
Downgrading from asterisk 13.29.x fixed the issue and it appears to be fixed in asterisk 13.30.0.
We have noticed it in 13.29.1 and 13.29.2, updating any of our systems to the current version breaks the ARI. The asterisk bug was marked fixed in 13.30.0.
