no retryable status codes provided

Error message

no retryable status codes provided

What it means

Returned by retryableStatusCodes when the retryable status codes setting is an empty string while a retry configuration is in effect — there is nothing to retry on, so the interceptor cannot be built.

Solutions

1. Provide at least one valid gRPC status code to retry, e.g. 'Unavailable'
2. Disable the retry configuration entirely instead of leaving it empty
