error: Error updating eth1 chain cache Timeout request

[come-maiz]

Describe the bug

I'm running lodestar from the unstable branch to test mev-boost.

I'm following these instructions: https://github.com/flashbots/mev-boost/wiki/Testing/fa8b3f72058255fe394066bab285a3e6a9be92fd#lodestar

When I start it to run the beacon node, this error appears:

$ ./lodestar beacon --network kiln --builder.enabled --builder.urls http://127.0.0.1:18550 --jwt-secret=/home/$USER/workspace/sec

The error appears like every minute.
It seems to be syncing, so this error does not seem problematic so far.

I'm running this with nethermind. I'm not sure if the issue is in here or there. Filing here to start digging.

Expected behavior

The beacon node syncs with no errors shown.

@come-maiz seems from the logs that the issue resolved and the sync move forward, we have a tracker issue to reduce/remove such harmless/intermittent/self resolvable error loggin #4348

Closing this issue for now as part of #4348
