Doing a dd in Symfony application display white page

[ruudk]

When I use dd from the VarDumper component, it shows a white page instead of the actual content.

Looks similar to #1021 but this is for Symfony.

What can we do to prevent FrankenPHP from displaying a white page?

Try calling:

header_remove("Content-Length");
dd('whatever');

FrankenPHP + Caddy will not send a response if the output doesn’t match the Content Length header.

If you still see the issue, then it may be something else.

I tried the snippet above, but still see a blank page.

You probably have some middleware adding the header to your response object.

I think it's a bug in Symfony:
