Nimbus CL < > Prysm VC incompatibility

[barnabasbusa]

Describe the bug

We are in the process to test cross beacon <> validator client compatibility, and found a bug when testing nimbus CL with prysm VC.

Prysm reports:

time="2024-04-05 12:15:11" level=info msg="Waiting for deposit to be observed by beacon node" prefix=client pubkey=0xa2e2d8384fc8 status="UNKNOWN_STATUS"

Nimbus reports:

nothing out of the ordinary

Snooper between cl <> vc reports:

It seems like prysm is stuck on requesting genesis state, and stops there.

Expected behavior

I would expect all client combinations would work.

Steps to reproduce

config.yaml:

participants:
  - cl_type: nimbus
    vc_type: prysm
additional_services:
  - dora
snooper_enabled: true
global_log_level: debug

kurtosis run github.com/kurtosis-tech/ethereum-package --args-file config.yaml

Could you please provide more information? There is no reason for VC to request genesis state from BN. But anyway i do not see from your issue that something requests for genesis state.
