Hi @chopeen. Azure Verified Modules do not explicitly support OpenTofu and we don't test with OpenTofu. This is the first issue I have seen where there is a difference between the OpenTofu and Terraform CLI implementations that is surfacing as an issue. This is very interesting to see and I will raise with the other AVM leads to get their thoughts. Unfortunately, there is nothing we can do to resolve this in the short term.

I was going to post exactly what @jaredfholgate did!

I suggest opening an issue on the opentofu repo to support this.

At the moment we are reliant on opentofu's compatibility promises. We will consider as a team if we need to change our position

If we choose to support both then it's a race to the bottom in terms of the features we can use.

I think you're both right - OpenTofu does support the removed block, but not the lifecycle meta-argument in modules - there is an open feature request https://github.com/opentofu/opentofu/issues/304 for such enhancement.

---

GitLab has deprecated support for the Terraform templates (see deprecate-terraform-cicd-templates) and stopped updating terraform binaries licensed under BSL; Terraform CI/CD templates will be removed completely in May 2025.

Can you please discuss the possibility of adding support for OpenTofu?
