For reference, serversideup/php:8.2-unit-v3.1.0 and serversideup/php:8.2-unit-v3.2.0 work without issue.

[jaydrogers]

Thanks for the heads up and the detailed message.

I will take a look into this. It's definitely only affecting unit only.

I have some other open source projects that I am trying to get out the door very soon, so let me swing back to this once I have some bandwidth.

Thanks for your patience! 👍

I ran into this issue today, hopefully #427 or #428 are enough to get this fixed.

[jaydrogers]

Setting return 0 fixed this, as suggested by @WoLfulus (b6daaea)

I left the return 1 out because I wanted the script to exit immediately on those.

This is currently on this PR:

• Nginx Unit upgrade to 1.33.0 and other bug fixes #452

But it will soon be merged into:

• v3.4 Release #445

I would appreciate some alpha and beta testing if you get the chance! Thanks a ton for your help!
