Azure Pipeline resources not triggering pipelines

Question

I have 2 azure pipelines, I want Pipeline2 to be triggered by Pipeline1, I used the 'resources' for YAML pipeline steps, but it didn't work.

I also tried the UI triggers, didn't work either.
Wondering if there could be an Org policy restricting this?

Both build and release yaml file is in the same folder, same Azure Project.

Branch: feature/release-pipeline

Pipeline1: infrastructure_build_testing

name: infrastructure_build_testing

trigger: none

Pipeline2: infrastructure_release_testing

name: infrastructure_release_testing

trigger: none

resources:
  pipelines:
  - pipeline: 'infrastructure_build_testing'
    source: 'infrastructure_build_testing'
    trigger: true
      # branches:
      #   include: 
      #   - feature/*
