Azure Devops Trigger from anotherproject and repo

Question

In REPO A on project A - yaml files of pipeline (central project for them) In Repo B on project B - Pipeline tab and code deployment location (IaaC let say).

pool:
  name: Pool_name

resources:
  repositories:
  - repository: Repo-A
    endpoint: Endpoint
    name: Project-A/Repo-A
    ref: main
    type: git
    trigger: none
  - repository: Repo-B
    endpoint: Endpoint
    name: Project-B/Repo-B
    ref: main
    type: git
    trigger:
    - main

stages:
- stage: stage-1
  displayName: stage-1
  jobs:
  - job: job-1
  displayName: job-1
  steps:
  - checkout: Repo-A
  - checkout: Repo-B
  - script: script-testing

As described in MS documentation, my trigger should work - Define a repositories resource .

I have tried to set triggers, ref's with different properties but nothing is workig. Configuration with

trigger:
  branches:
    include:
    - main

also was tested. Nothing has changed.

What I want to achieve is to trigger this pipeline located in repo A to run when main of Repo-B will be updated.

They are in the same ADO Organization, on different projects. Same endpoint use for both projects.

Pipelines started to work as expected after deleting the Endpoint. Working config:

pool:
  name: Pool_name

resources:
  repositories:
  - repository: Repo-A
    name: Project-A/Repo-A
    ref: main
    type: git
    trigger: none
  - repository: Repo-B
    name: Project-B/Repo-B
    ref: main
    type: git
    trigger:
    - main

stages:
- stage: stage-1
  displayName: stage-1
  jobs:
  - job: job-1
  displayName: job-1
  steps:
  - checkout: Repo-A
  - checkout: Repo-B
  - script: script-testing
