Yep, same error message here using images dunglas/frankenphp:latest-php8.2-alpine or dunglas/frankenphp:latest-php8.3-alpine (also on MacOS+Silicon)

[dunglas]

This looks like a bug introduced in the newly supported apache_request_headers function.

Could you temporarily downgrade to the previous version or don't call this function?

[Danielss89]

Yes, downgrading to 1.0.3 seems to be working

[ma4nn]

@dunglas thanks, yes seems like this is the reason - dunglas/frankenphp:1.0.3-php8.3-alpine is also working fine for me 👍
