Cannot use terraform stacks

Terraform Version

Terraform v1.13.0-alpha20250521
on darwin_arm64
+ provider registry.terraform.io/cloudflare/cloudflare v5.4.0
+ provider registry.terraform.io/hashicorp/aws v5.97.0

Terraform Configuration Files

This happens just loading a plugin, don't think config is relevant here.

Expected Behavior

I would have expected the cli program to offer me verbs to manage Terraform Stacks.

Actual Behavior

Error, unable to fetch plugin payload.

Steps to Reproduce

1. Use Terraform cloud
2. Try a stacks command like terraform stacks -help

Thanks for this report, I'll raise it with the appropriate team.

Hi @henrythor,

There hasn't ever been a stacks command in the CLI ... until today! Terraform v1.13.0-alpha20250604 contains the first iteration of the stacks command if you are interested in testing it out.

Hi @henrythor,

It seems the command interface is not yet ready, so while stacks exists in this alpha it's not yet operational. Since things are going to be in flux until the code freeze at the beta, that would probably be batter point to try this out again, unless you intend to be more involved with the feature development. Until that point, many things are expected to not work or change.

The initial fix for this error will be included in #37211

Thanks!
