Provider operator ID is required

Error message

Provider operator ID is required

What it means

A blockchain provider identity must include a nonempty operator_id; the check trims whitespace, so blank values fail. The operator_id distinguishes the operator entity running the provider from the provider itself and is required for identity resolution and failure-domain bookkeeping.

Solutions

1. Set operator_id to a nonempty identifier for the operating entity in the identity/config
2. Ensure the environment variable or secret backing operator_id is exported and nonempty at startup
3. If identities are templated, add operator_id to the template and validate before deploy
4. Run the identity validation early in startup so missing identity fields surface before use

Example fix

// before
{"provider_id": "alchemy-mainnet", "operator_id": ""}
// after
{"provider_id": "alchemy-mainnet", "operator_id": "ops-team-alpha"}

When it happens

Trigger: Validating a BlockchainProviderIdentity whose operator_id is missing, empty, or whitespace-only; the provider_id check passes first, so this fires only for identities that already have a valid provider_id.

Common situations: Config templates with operator_id left blank; multi-operator setups where the operator field was never filled for a new deployment; deserialization from YAML/JSON where the key was omitted and defaulted to an empty string; environment variables not exported before launch.
