Error running pipeline from action

### Information
When trying to run a pipeline from a GitHub action the below error is produced. I can confirm the URL works as I use it to access my project. The project is private, not sure if that helps.

### Error
##[error]Failed to parse project url: "https://dev.azure.com/powerful-it/Monitoring/".
Specify the valid project url (eg, https://dev.azure.com/organization/project-name or https://server.example.com:8080/tfs/DefaultCollection/project-name)) and try again.

### Action
pipeline:
name: 'DevOps Pipline'
needs: [terraform]
runs-on: ubuntu-latest

defaults:
run:
working-directory: ./mon-app

steps:
- name: Run
