Unexpected Error from plugin.(*GRPCProvider).UpgradeResourceState #186

Open james1miller93 opened 2 years ago

james1miller93 commented 2 years ago

We're receiving intermittent errors from the provider when running terraform plan against crd resources in a cluster which are managed using the provider.

We only seem to see these errors in <10% of plan operations and they seem to occur on resources which are not being modified in the plan.

I have a full TRACE log for a failed job, so can provide more log data if needed.

Wanted to mention that we are experiencing the same issue and it is introducing flakiness into our pipelines :(

@gavinbunney, I'm no go expert but could this not be solved by putting a retry & back off in the ReadContext

We're also impacted by this issue and it's causing intermittent pipeline failures for us like @mhulscher.
