L1 RPC endpoint protected by basic auth is not working

[olivbau]

My L1 RPC endpoint is protected by a basic auth. In my .env file I have something like this:

# L1 node to run fault detection against
FAULT_DETECTOR__L1_RPC_PROVIDER=https://username:[email protected]


# Node to get chain data from (if SYNC_SOURCE is "l1" then use L1 node, etc.)
DATA_TRANSPORT_LAYER__RPC_ENDPOINT=https://username:[email protected]

It doesn't seem to work, here is the DTL error:

Do you have any idea how I can get around this problem?

[olivbau]

It seems that there are envs for this problem: https://github.com/ethereum-optimism/optimism/tree/develop/packages/data-transport-layer#configuration-1

envs:

• DATA_TRANSPORT_LAYER__L1_RPC_USER
• DATA_TRANSPORT_LAYER__L1_RPC_PASSWORD
• DATA_TRANSPORT_LAYER__L2_RPC_USER
• DATA_TRANSPORT_LAYER__L2_RPC_PASSWORD

I'll try to create a PR to support this envs

[olivbau]

Unfortunately it seems that there are no user and password options for FAULT_DETECTOR__L1_RPC_PROVIDER and OP_NODE__RPC_ENDPOINT Do you have any ideas?

[olivbau]

I tried to use DATA_TRANSPORT_LAYER__L1_RPC_USER and DATA_TRANSPORT_LAYER__L1_RPC_PASSWORD for DATA_TRANSPORT_LAYER__RPC_ENDPOINT. And use https://user:password@host:port syntax for FAULT_DETECTOR__L1_RPC_PROVIDER and OP_NODE__RPC_ENDPOINT.

Here is what I changed (just add DATA_TRANSPORT_LAYER__L1_RPC_USER and DATA_TRANSPORT_LAYER__L1_RPC_PASSWORD support) https://github.com/smartcontracts/simple-optimism-node/compare/main...olivbau:simple-optimism-node:basicauth-support

But it's not working, here is the type of errors I get on the DTL:

}

Do you have any ideas on how to fix this problem?
