How to authorize pool in Azure?

Question

Trying use my own create agent for the first time, met with this:

The pipeline is not valid. Could not find a pool with name Default. The pool does not exist or has not been authorized for use. For authorization details, refer to https://aka.ms/yamlauthz.

I have 2 agents in the Default pool in idle status. I follow https://aka.ms/yamlauthz but it tells me nothing about how to authorize the pool.

How do I authorize the pool?

Answer 1

If clicking on 'Authorize' does not help, it may be because the agent pool has not been added to the project, only to the organization (agent pools are shared across organizations).

Go to Project settings -> Agent Pools -> Add pool, then Pool to link: Existing and select the agent pool to add it.
