问题
Today, I started getting this error sporadically. Google pubsub error codes talks about only HTTP error codes. Does anyone know about this error?
ERROR Error: The service was unable to fulfill your request. Please try again. [code=8a75]
回答1:
This error code is retryable, and can be safely expected. Automating your code to automatically retry with backoff, or to use one of the official client libraries, which automatically retry on these errors with backoff is the recommended solution.
In general these errors should be independent, meaning after a retry or two the odds that your RPC fails should be very low.
