Is there a way to have more verbose debugging?

I am PoC'ing Tapir, and unable to upload a module.

i've got the deploy key scoped to the test namespace, and attempting to upload it with this command

curl -XPOST -H 'x-api-key: 4v5eupdxxx' --fail-with-body -F "archive=@module.zip" "https://xxxx.eu-west-1.awsapprunner.com/terraform/modules/v1/test/vnet/azurerm/1.0.0

but response is 401

curl: (22) The requested URL returned error: 401

what am I missing?
