Crash running terraform show -json plan.tfplan

[mikesir87]

Terraform Version

Terraform v1.0.1
on darwin_amd64

Terraform Configuration Files

Not really sure what part is relevant or not and have a lot of Terraform being used. I've tried to make a smaller scoped project to reproduce the bug, but have had trouble doing so.

Debug Output

Crash Output

Looks mostly the same as the debug output, but here you go...

https://gist.github.com/mikesir87/baead99ece361545479f829593af8e39

Expected Behavior

The command to work successfully

Actual Behavior

We get an error indicating panic: value is marked, so must be unmarked first, which is hard to diagnose.

Steps to Reproduce

Hard to know, as it seems to be only one of our pipelines.

Additional Context

• We do NOT get the error when using 0.15.5 but do on either of the current 1.0.x releases.
• Running terraform show plan plan.tfplan without the JSON flag exits successfully

References

Not sure yet. I took a look at #28903, but that doesn't appear to be exactly related. And it still occurs in the 1.0.1 release which includes the MR fixing it.

Ah and thank you! I did some searching, but apparently didn't find that one. Thanks @jbardin!
