Cannot invoke cancel/discard run via terraform CLI

[leg100]

Terraform version: 1.3.7

When I cancel a run via the terraform CLI, pressing ^C:

Waiting for 3 run(s) to finish before being queued...
^C
Interrupt received.
Please wait for Terraform to exit or data loss may occur.
Gracefully shutting down...

Do you want to cancel the remote operation?
Only 'yes' will be accepted to cancel.

Enter a value: yes

The same occurs when the CLI discards a run.

It looks like this broke with this commit to the go-tfe lib:

hashicorp/go-tfe#388

This lib is used by the terraform CLI for iteraction with TFE/C and OTF.

I also experienced this and was thinking of reporting it - but hold back given my other "lock" issues reported recently and not being sure if they have an influence on this behavior 🙂
