## Issue Addressed Fixes #2118 ## Proposed Changes Removes the default value in clap for `--beacon-nodes`. This was causing issues with cli picking `--beacon-nodes` default even when not specified and overriding `--beacon-node`. Seems like it was more evident with docker setups because it doesn't use the default `http://localhost:5052` option. Edit: we already set the default to `http://localhost:5052` here so this shouldn't break any existing setups. https://github.com/sigp/lighthouse/blob/9ed65a64f8fc518c98b381e628556df9bf906acb/validator_client/src/config.rs#L58 ## Additional info Tested this with docker-compose and binaries. Works as expected in both cases.
