Error when trying to set pipeline pool to Default agent pool using azure-pipelines.yml

Question

I followed the documentation for setting pool via Pipelines Schema Docs and set it as such pool: Default. This should direct pipelines to use the Default pool:

However, I keep getting this error:

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.

As far as I can tell it should be authorized.

I also tried:

pool:
  name: Default

try changing your branch to any other branch and saving your pipeline and changing it back and saving it. run pipeline after that — 4c74356b41, Mar 29 '19 at 19:40
@4c74356b41 I updated my post to contain my full yml file. I am currently triggering builds off of two different branches. It sounds like your recommendation is based on the classic pipeline editor not a yml based pipeline? Editing my pipeline only allows me to update my azure-pipelines.yml from the browser. If I try to manually queue a build off of any of the branches in my repo I get the same error. — Jason G., Mar 29 '19 at 19:57
click on the cogwheel on the top right and click variables, you'll get to the old ui and there you can do what I'm saying. — 4c74356b41, Mar 29 '19 at 20:02
@4c74356b41 Selecting Default from the Agent Pool dropdown in the old UI and saving fixed it. It didn't seem to make any changes to my yml file though. — Jason G., Mar 29 '19 at 20:10

I had the same issue for 'Azure Pipelines'. It turned out that the project did not had Azure Pipelines pool added in the Agent pools. You can configure this in Azure DevOps at the Project Settings. (gear icon bottom left)

This was my issue too. I had created the agent pool at the organization level but not added it to my project. – Rye bread Apr 21 '22 at 08:17

You can refer to this link: https://aka.ms/yamlauthz to fix this issue ;)

Try changing your branch to any other branch and saving your pipeline and changing it back and saving it. Run pipeline after that.

To accomplish this click on Edit on the top right of the Pipelines/Build page. You will be presented with the YAML editing tool. Now click the hamburger icon on the top right and select Variables. This will take you to the classic editor. From the classic editor click on the YAML tab. Under the YAML tab you can select Get sources and change you default branch.

The question does not really state if you are dealing with Azure DevOps Services or with Azure DevOps Server. With Server this did the trick for me:

pool:
  name: 'myPoolName'
