Terraform plan -json in TFC with remote exection mode


When using TFC with the remote execution mode, there seems to be actually no way to retrieve a json version of a plan.

the command terraform plan -json doesn’t output the expected level of info.
actually, it seems to stream to logs from the remote execution, but not in json format (as we would expect)

and the commands:

terraform plan -out plan.bin
terraform show -json plan.bin

cannot work because “Saving a generated plan is currently not supported” with the remote execution mode.

what could we do to improve this situation ?
is there any known workaround ?

thanks a lot.
