@LinuxSuRen Can you give more details on this issue so that we can reproduce this?

hi @ArjunMenon-bit , I'm not sure if I understand it correctly. I thought I could give an environment with the given compose file which is in the URL above. But I got a 500 error response when I clicked the above button (Try in PWD).

@LinuxSuRen try renaming .yaml to .yml
it could due to the code logic expecting .yml
