Everything was working good until one day while trying to pull repository from Azure Dev Ops I’m getting below error:

In our case, we do not want to raise a PR in GitHub. Instead, we prefer to use cherry-pick to merge files from the cherry-pick-test branch to the main branch and keep the code up to date.

I cloned a month ago a Github public repo directly into a new private Azure DevOps repo, by using https://learn.microsoft.com/en-us/azure/devops/repos/git/import-git-repository?view=azure-devops , since we are implementing new software which is hosted in a Github public repo. The reason for saving the code also in ADO is since we have few parameter files that we need to modify.
After this original clone directly from GitHub to ADO, I cloned locally on my laptop and created a new branch for DEV based on main, by adding one commit that contain 4 yaml files : 2 new parameter files and 2 updated files. Then pushed DEV branch to ADO.
