[Bug]: Terraform crashed! This is always indicative of a bug within Terraform.

What happened?

Hi 👋

It looks like the latest revision of Terraform snap (released today) is not working. When trying to run terraform plan or terraform apply it crashes.

Filling a bug here first, but not sure if this is an upstream issue that should go to https://github.com/hashicorp/terraform/issues instead.

Workaround for now: sudo snap refresh --channel="latest/stable" --revision="661" terraform && sudo snap refresh --hold terraform

What should have happened?

With terraform plan it should refresh and show the plan. With terraform apply it should refresh, show the plan and ask for "yes/no".

https://github.com/hashicorp/terraform/issues/34976 Still keeping this open as I believe it will need a new snap revision once fixed.

This should now be solved :) https://github.com/snapcrafters/terraform/issues/106
