(*models.Error) is not supported by the TextConsumer

[ianlewis]

We're seeing this error in a non-trivial number of our e2e test runs w/ slsa-github-generator.

&{0 } (*models.Error) is not supported by the TextConsumer, can be resolved by supporting TextUnmarshaler interface

As with #801 it seems to be a transient error. A quick Google search returned go-swagger/go-swagger#1929 which seems to be unresolved in the swagger library but there are some clues there as to potential ways to work around it.

I'm suspect that you're getting a 429 response due to rate limiting, but since that is formatted by nginx as HTML (instead of JSON which is what the rekor client expects by default).

be91b71 (which is in 1.0rc) changes the underlying HTTP client to quietly attempt retries according to the Retry-After headers returned by the gateway). That probably won't definitively fix the error you're reporting here, but should make it happen drastically less often.

@ianlewis has upgrading to rekor v1.0.0 helped in this?

[ianlewis]

@bobcallaway I think we're still evaluating. I don't think we have a release with it included but I'll see how often it occurs in our e2e tests this week.

@bobcallaway We actually didn't update Rekor to 1.0.0 in in slsa-github-generator yet. We only had updated it in the verifier. Hopefully slsa-framework/slsa-github-generator#1121 will get merged in the next day or so and we'll see results.

We've upgraded to rekor 1.0 and haven't seen this error since upgrading. Closing.
