Hi @DavidHermes,

That isn't a user-facing error from Terraform, are you experiencing a problem with Terraform planning or applying the configuration?

[DavidHermes]

It happens when applying a configuration.

I can confirm that this issue happens in some deployments. It seems to happen randomly, sometimes I get this error, but then re-running terraform apply with the same exact configuration works. Platform is Ubuntu x64.

This started happening after a recent Terraform update, but I can't pinpoint the exact version. It does not seem to be provider-related, as downgrading to an older Terraform version (1.6.x in my case) fixes it.

Hello, the question we're waiting on is if there is an error reported by Terraform in the UI, or if Terraform is not behaving correctly. The log message above is not intended for the end user, it is probably an erroneous log message from an upstream library, but I'd like to rule out any possible Terraform issues before sending this over to other maintainers.

Thanks!
