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

Terraform crashed! This is always indicative of a bug within Terraform.
A crash log has been placed at "crash.log" relative to your current
working directory. It would be immensely helpful if you could please
report the crash with Terraform[1] so that we can fix this.

When reporting bugs, please include your terraform version. That
information is available on the first line of crash.log. You can also
get it by running 'terraform --version' on the command line.

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

Expected Behavior

Terraform successfully initialized, or fail gracefully with clear message on what is missing.

Actual Behavior

Terraform crushed

Steps to Reproduce

$ unset HOME
$ terraform init

Additional Context

It seems v0.12.8 introduced a dependency on HOME environment variable to exist. In some testing envs (like Tox) this variable is _not_ passed to the testing process.

Any update on a nicer error? cc @jbardin @mildwonkey @alisdair

@ofek @mindw I've been going through and re-triaging all the issues labeled crash in this repository, and I noticed that some variant of this has been reported several times. I've been consolidating all of them into https://github.com/hashicorp/terraform/issues/24520. I just noticed this, and it looks like an identical crash message to 24520:

From #24520:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x2449596]

goroutine 1 [running]:

I'm going to close this and treat #24520 as the primary issue for this bug. If you're interested in watching for the resolution, please follow and 👍 that issue. Please let me know ([email protected]) if you think I've missed something and this should a different issue.
