MaxListenersExceededWarning: Possible EventTarget memory leak detected.

[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

It is now syncing, so this error does not seem problematic so far.

Expected behavior

The beacon node runs with no errors shown.
