unknown provider "registry.terraform.io/-/stateful" (we don't use this) about terraform-resource HOT 2 CLOSED

ok; looks like the plan files for staging and prod are using 0.12-style provider names in the state files they are trying to upload; snippet of diff dev-plan.json staging-plan.json

is it safe to delete the plan state files? Presumably they would get re-created anyways with the new provider styles.

I did it anyway; delete the plan files in S3 (we are using S3 remote backend) and delete the entries in Dynamo lock table, then re-running plan and it succeeded. Will close this since it's fixed, but would love to hear maintainer's ideas about how we could have ended up with 0.12 plan files which only now are breaking (an earlier test, ~Nov 2, same repo but no such error; seems weird to me that it's come up now).
