Hey :)
Our application upgraded from 0.12.3 .. 0.12.4 today. Then our CI failed with new translation keys untranslated.
After 1 hour of debugging it seems that it's this upgrade that cause the error.
Also, we had to force the php-translation/extractor package in 2.0.3 to fix the error.
Maybe something related with this service definition ?
The goal of this issue is to inform you.
Thanks for your work
Cheers
