GitHub Actions Cache Failure

[erikreinert]

Overview

When trying to upload cache to GitHub Actions for the store, we sometimes see an intermittent error:

Error: Stream error: Status { code: Internal, message: "failed to push artifact: Status { code: Internal, message: \"failed to save cache: \\\"error sending request for url (https://acghubeus1.actions.githubusercontent.com/NhoeVa0TEpxJHzqBO2XiaAx3oxpeIfiZ3k6aA2CduZgd2zygZ5/_apis/artifactcache/caches/3151)\\\"\", metadata: MetadataMap { headers: {\"content-type\": \"application/grpc\", \"date\": \"Thu, 30 Jan 2025 02:12:42 GMT\", \"content-length\": \"0\"} }, source: None }", source: None }

Because of this any following pipelines that try and save the cache again will fail with this error:

Error: Stream error: Status { code: Internal, message: "failed to push artifact: Status { code: Internal, message: \"failed to reserve cache: \\\"Unexpected status code: 409 Conflict\\\"\", metadata: MetadataMap { headers: {\"content-type\": \"application/grpc\", \"date\": \"Thu, 30 Jan 2025 02:47:36 GMT\", \"content-length\": \"0\"} }, source: None }", source: None }

We need to investigate how to safely skip or fail on this.

Possible Options

• skip the cache entirely
• remove the cache reservation and retry
