Provide a brief description of the functionality you're trying to implement and the issue you are running into.

Lens uses:

      EN_DA_CLIENT: "Avail"
      EN_DA_AVAIL_CLIENT_TYPE: "FullClient"
      EN_DA_BRIDGE_API_URL: "https://bridge-api.avail.so"
      EN_DA_TIMEOUT_MS: "20000"
      EN_DA_API_NODE_URL: "wss://mainnet.avail-rpc.com"
      EN_DA_APP_ID: "26"

For v28.2.1 above setting were find but after upgrading to v28.5.0 is gives:

Error: DA client config is missing

Tried using this in the docker config like:

  EN_CONSENSUS_CONFIG_PATH: "/configs/mainnet_consensus_config.yaml"
  EN_CONSENSUS_SECRETS_PATH: "/configs/mainnet_consensus_secrets.yaml"

da_client:
  avail:
    bridge_api_url: https://bridge-api.avail.so
    timeout_ms: 20000
    full_client:
      api_node_url: wss://mainnet.avail-rpc.com
      app_id: 26    

da:
  client: Avail
  seed_phrase: toilet extra

What am I missing? I prefer using environment variables like it was running on v28.2.1

Hmm, configuration through environment variables shouldn't be affected. Can you share your Dockerfile? Or at least the part where you set up configuration?

Docker is exactly like this
Except I tried to update to "matterlabs/external-node:2.0-v28.5.0"
(Reverting back to v28.2.1 doesn't work because of some migration that has happened)

The error after starting is like this:

2025-06-10T14:44:09.415104Z  INFO zksync_external_node: Main node URL is: "https://rpc.lens.xyz/"

Error: DA client config is missing

Can you try to add EN_DA_MAX_BLOCKS_TO_LOOK_BACK: "5"? That's a new field in the config and seems like we forgot to add a default when configured through envvars.

Hi Itegulov, that was the missing part and now it works again! Also thank you for the fast replies, appreciate it!
