Azure DevOps pipeline trigger issue message not going away - azure-devops

Question

Our team is implementing an Azure DevOps testing pipeline. After our initial commit to create the pipeline .yml file this error message was displayed. After looking into it, I realized I forgot to include the trigger in the .yml. However after adding, it this error message hasn't gone away. The pipeline is working as expected though, we are just using a manual trigger which is shown below. The only listed issue is from the our original commit. Is there a way I can acknowledge this error to make it go away or am I potentially missing a different error that I just haven't noticed yet? Thanks for any help in advance, please let me know if I can provide any additional information.
Here are the error messages that I am seeing when I view the runs of that pipeline. I also included a screen shot of how I'm setting up my trigger.
Edit: As request I included the actual .yml file code below with slight naming modifications. We do have some custom plugins such as creating files for files that are untracked but still needed to be created. So you might need to remove those to test this.

Edit (2): Included below is a screen shot of what I am using for trigger settings now, originally it was unchecked. Checking it doesn't seem to have any affect though.

Answer 1

I had the same and was about to curl up in a ball and cry when I found out the real issue. As the wonderful message is saying, it has absolutely nothing to do with trigger :)
I assume you created a new branch with your YAML file for testing purpose before merging it to master. So you need to setup your build to point to this branch because the file doesn't exist on your main branch.
Here the steps :
Edit your pipeline
Click the 3 dots on top right > Triggers
Click YAML tab > Get sources
Change the 'Default branch for manual and scheduled builds' to point to the branch where your .yml file is

Answer 2

So we gave up on this problem since it wasn't having any effect and we couldn't find the problem. After about a week or two it just stopped showing up. So I assume this was just some quirk with the Azure DevOps and not a problem with the pipeline itself.

According to your description, this issue looks more like an episodic issue. In YAML files, you don't have to include triggers. YAML pipelines are configured by default with a CI trigger on all branches. You can create a new pipeline and copy your YAML file to see if there are still any error messages.
Or, the issue could come from Classic UI triggers. On the pipeline editing page, select More actions-> Triggers.
Then you can check if there is anything illegal. If you want to use the trigger in the YAML file, leave the '
Override the YAML continuous integration trigger from here' check box off.
