Lychee 7.0.1 not starting up - WARN Caddyfile input is not formatted; run 'caddy fmt --overwrite' to fix inconsistencies.

[hDoubleU71]

Installed version 7.0.1 in Docker directly with the supposed docker compose file from the start page, but getting the error:
WARN Caddyfile input is not formatted; run 'caddy fmt --overwrite' to fix inconsistencies.
INFO Error: loading initial config: loading new config: frankenphp app module: start: failed to initialize workers: too many consecutive failures: worker public/frankenphp-worker.php has not reached frankenphp_handle_request().

What is missing?

WTF.

The caddy issue you can ignore safely.
What is more worrying is the immediate crash. I tried replacing :latest with :edge and I do see the same behaviour.

Got it.

The reason is your key: VGhpc0lzQW5CYXNlNjRLZXlGb3JMeWNoZWU=. It is too short.
If I base64 decode it and send it to hex I get:
546869734973416e4261736536344b6579466f724c7963686565 which is 52 characters or 26 bytes. Lychee need keys of length 32 bytes.

Thanks you for the heads up, I will add a check to validate the key-length.

Here is a command that generates a key of 64 bytes.

openssl rand -base64 32
