Debug output

Error: rpc error: code = Canceled desc = context canceled

Error: rpc error: code = Unavailable desc = transport is closing

Panic output

_No response_

Expected output

Plan to succeed

Actual output

Error messages as described above

Steps to reproduce

1. Submit a change to VCS
2. This triggers a plan run in terraform cloud

Additional factoids

I've pulled the state from terraform cloud and ran terraform plan locally without any issues.
Opened a pull request pinning the provider version to 2.18.0 and plan ran without issues on terraform cloud.

Thanks @KyleNesium

I saw that issue but seems somehow unrelated. I managed to run a successful plan with provider version 2.19.1 locally (Terraform v0.14.5 for Darwin), without crashes.

This seems to affect terraform cloud only.

I'm getting a bunch of following errors:
Error: rpc error: code = Unavailable desc = transport is closing
Error: rpc error: code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: write unix @->/tmp/plugin771003864: write: broken pipe"
Error: rpc error: code = Canceled desc = context canceled

And part of crash report:

panic: runtime error: invalid memory address or nil pointer dereference

Started to happen today with newest provider 2.19.1.

Works ok with 2.19.0.

[lneves75]

I can also confirm that first failed run was seen ~5h ago and previous successful run was ~20h ago.
That means that v2.19.0 was used in successful runs and once v2.19.1 was released we started to see these errors.

I will amend the title.

@KyleNesium I stand corrected.

After looking into this carefully I noticed I was still using the cached version of the provider (2.18.0) since I didn't run terraform init -upgrade locally.
Removed cached version, wiped .terraform to start anew and removed version constraints from the provider.
I managed to reproduce #988

Using v2.19.0 works as mentioned by others. Closing this issue as it's a duplicate.
