What are the potential blitline error codes?

[NoelAbrahams]

Hi,

We use Blitline with long polling in order to process images for our website.

We would like to tighten up error handling around this interaction. Specifically we'd like to implement retry logic if a particular job fails. In order to do that we need to know the complete list of error codes and their descriptions.

I'm aware that interaction with Blitline is via HTTP, hence most likely we are looking to deal with HTTP status codes. But are there any special cases, for example, do you return a 503 or 429 when the service is overloaded?

An exhaustive list of error codes will be very helpful.

Thanks.
