Unable to execute a pipeline from a repo in other Azure Devops repo

Question

Hi,

I have my source code in an azure devops repo.

Let's say- Organization - OrgA, Repo - RepoA, Project to be built- ProjA

I happen to have created another azure devops organization. Organization - OrgB

Now, I wanted to create a pipeline in OrgB to build ProjA.

I was referring to https://learn.microsoft.com/en-us/samples/azure-samples/azure-pipelines-remote-tasks/azure-pipeline-remote-tasks/

But I have ended up at this error: VS800075: The project with id 'vstfs:///Classification/TeamProject/30c79f79-ba4b-4625-b4fa-d5db3a225b3b' does not exist, or you do not have permission to access it.

Please help here.

Thanks
