Checkout Submodules in another Project in Azure DevOps Repository

Question

I'm trying to checkout a submodule from another project in azure devops.

steps:

- checkout: self
  submodules: true
  persistCredentials: true
  clean: true

Checking out another repository in the same project works.

GOAL

Add as submodule REPOSITORY A in REPOSITORY B.

However i get the error:

Cloning into 'E:/build/Agent5/_work/16/s/.azuredevops'...
fatal: could not read Username for 'https://dev.azure.com': terminal prompts disabled
fatal: clone of 'https://dev.azure.com/ORGANIZATION/PROJECTA/_git/REPOSITORYA' into submodule path 'E:/build/Agent5/_work/16/s/.azuredevops' failed

How can i achieve this using YAML in Azure DevOps Repositories?

Answer 1

There was on option "Limit job authorization" that was checked on by default, in the Project Settings (bottom of the the left menu).

Turning it off solved the issue.

And FYI I just had this to be added in the yaml, under steps::

- checkout: self
  submodules: true
