Key generation (TypeKeyGen) fails because node IDs do not match

TypeKeyGen is the callback request type that the TSS Node sends to your callback server to create new key shares. The request payload includes a node_ids field that lists the TSS Node IDs of the key share holder group for the task. For details, see the TypeKeyGen request request_detail node_ids field in Callback request and response formats. Likely cause: The TSS Node IDs configured for your node do not match the TSS Node IDs of the key share holder group for the key generation task. Remediation:
  1. Verify the node IDs in your TSS Node configuration.
  2. Compare them against the node_ids listed in the TypeKeyGen request_detail.
  3. Correct any mismatch so that every node ID matches the key share holder group.
  4. Restart the TSS Node and retry key generation.
