LinkAce with Caddy on Arch Linux ARM

[Lanie-Carmelo]

Hi all. I'm trying to get LinkAce going on my Raspberry Pi 500 running Arch Linux ARM, and I'm having some trouble. I'm hoping someone can help.
I'm trying to use LinkAce in Docker behind Caddy and Authelia, neither of which is in Docker. LinkAce seems to be starting its own Caddy instance, which worried me at first, but now I don't think that's the issue.
I'm getting 500 errors when trying to access LinkAce both locally and through Caddy. These are some of the logs I'm seeing:

My Docker-Compose file looks like:

volumes:

I've defined all relevant variables in my .env file.
Can anyone help me figure out how to fix this? Thanks.

Hi, please add APP_DEBUG=true to your .env file and try again. The error message should become more detailed.

[Lanie-Carmelo]

I put APP_DEBUG=true in my .env file and restarted the containers. This is what I see now:

And what is shown in the browser?

[Lanie-Carmelo]

@Kovah this is what I see when I try to go to my LinkAce instance in a web browser. It occurs both with my Raspberry Pi's IP and the port LinkAce is set to listen on, and when going to the domain I have set up for LinkAce, https://bookmarks.laniecarmelo.tech.

Oops! An Error Occurred
The server returned a "500 Internal Server Error".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

[Lanie-Carmelo]

I just tried setting APP_ENV=development and generating the app key with docker exec linkace php artisan key:generate, and that seems to have fixed things. It's now running correctly.
