Create Morpheus Terraform blueprint

I want to create Terraform blueprint in Morpheus. I am using blade Provisioning/Blueprints then I am trying add new Terraform blueprint, I want to use .tf file stored in Azure Devops repo (.tf file is ok, I tested it in azure, working as expected). When I select all required options in Blueprint wizard, populate all wizard fields, it looks like Morpheus doesn’t see/list files stored in the azure devops repo, when I am trying to click on " Complete " button I can see the error message “error loading .tf files from repository” . Integration has been performed properly. Using Provisioning/Blueprints I am able to create ARM blueprint and select .json ARM templates file stored in the same repo as .tf files.
