Expected Behavior

terraform show should successfully output the current state

Actual Behavior

running terraform show seems to output the resources in state, but not the output values associated with state before crashing and throwing the error below.

Steps to Reproduce

terraform show on a project that otherwise works fine with 1.3.7.

Additional Context

Hoping this is enough to share. I don't have a ton of time at the moment to comb through the full debug trace and make sure I'm not making public anything that shouldn't be public, but wanted to log the issue because I've never seen it before, it seems to effect 1.4.0 (I rolled back to 1.3.7 to get around the issue), and it said this was always indicative of a bug within Terraform.

Edit: The project was initially on 1.3.7; I haven't validated 1.3.8 or 1.3.9 I didn't notice they had been released until just now. 😂

I simply tried to do a terraform show and received the output provided. It seems to output most (all?) of the state resources, but fails before it can print the output values within the state and hard crashes. If there is more information I can provide, please let me know if the debug trace is known to output any secrets or org specific details that should not go into a public issue log without proper sanitization. Thanks.

I too am receiving this with 1.4.0.

In my case, I'm trying to terraform plan -destroy a db server in Azure.

Last few lines of the log in my case indicate this is happening after the plan operation itself completes, immediately after trying to delete the state file lock as indicated by the snippet below:

2023-03-13T14:50:11.609-0500 [INFO]  backend/local: plan operation completed
2023-03-13T14:50:11.609-0500 [DEBUG] DELETE https://gitlab.com/api/v4/projects/37833340/terraform/state/dev-centralus-01-postgres/lock

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform.
Please report the crash with Terraform[1] so that we can fix this.

When reporting bugs, please include your terraform version, the stack trace
shown below, and any additional information which may help replicate the issue.

Interestingly, this only started to appear after I added drop_cascade = true to a resource. When I remove it, this doesn't happen. That parameter is specific to the cyrilgdn/postgres provider and postgres_extension resource.

Terraform team, In comparing my log above to the OP's log, this seems to be happening in a different part of the code from OP and so it may be a separate bug. Please let me know if that's the case and I will open a new issue.

[tspearconquest]

Downgrading to 1.3.9 worked around this failure for me also.

[jbardin]

@tspearconquest, that is a different stack trace, and resolved in #32810
