External Auth Script does not start 21.12

[wahur666]

Hello,

I have some issues with the external auth script execution, with the version 21.12. This script still runs with 21.04 version. I attach an output from the docker container. Some info is redacted, but, if I run the script what should the program execute, it just runs fine outside. Any help would be appreciated.

Sincerely.

Docker volume was read only, and the script running could not write it. Solved.
