Whitelabel Error Page

[papierkorp]

I tried the Rest (ghcr.io/jodconverter/jodconverter-examples:rest) Version in a kubernetes Cluster (Node Version: v1.26.1) and got the following Error Messages:

java.lang.IllegalArgumentException: Invalid character found in method name [0x160x030x010x010x000x010x000x000xfc0x030x030xe030x1dm0x180xe60xe2Z0xd90xee0xe20xf80xc10x0e0xcf0x17uX&c0xa7kK0x1fb0x98\a0xea0xf50xf90xc0 ]. HTTP method names must be tokens

The GUI Version is working fine.

Please try this locally and reduce it to a minimum and tell us how to reproduce. So no k8s, CNI or CSI and even more important no ingress

I think I opened the Issue too fast (sorry :/). It seems to be working fine despite the error messages from above.

There was also a mistake on my part. I used http://localhost:8080, but should have used http://localhost:8080/swagger-ui.html. Maybe you can add the correct Link for swagger.

Thanks for the fast response anyway.
