statefile: Ignore unknown check results on decode#33818
Merged
Conversation
Terraform 1.5 introduced a new check result kind, which causes a decode failure when read by Terraform 1.3 and 1.4. This means that a 1.5+ state file cannot be read by the `terraform_remote_state` data source in 1.3 or 1.4 series. Aborting state decode at this point isn't strictly necessary, as we don't stand to lose important data by failing to round-trip these check results. Instead we can ignore those check results, allowing decode to elide them from the state. This has no negative effect on the remote state data source, which only exposes root module outputs anyway.
