Troubleshooting PAT based checkout and push to another repo in another account

[kombos]

I'm trying to create a github repo action such that pushing / merging to main branch of this repo A, belonging to github account M, triggers a push of the code to another repo B, belonging to github account N. I've created a PAT in account N, with full access to all repos and all options (just to be sure access isn't the problem), and stored this token value in the secrets of account M. Now i'm using this workflow file

name: Sync to Account N

on:
  push:
    branches:
      - main

jobs:
  sync:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Set up Git
        run: |
          git config --global user.email "actions@github.com"
          git config --global user.name "GitHub Actions"

      - name: Print Git version
        run: git --version

      - name: Add remote target
        run: |
          echo "URL: https://${{ secrets.PATVALUE }}@github.com/accountN/repoB.git"
          git remote add target https://${{ secrets.PATVALUE }}@github.com/accountN/repoB.git
          git remote -v

      - name: Test remote with verbose output
        run: |
          GIT_TRACE=1 GIT_CURL_VERBOSE=1 git ls-remote target

the error coming in 'Test remote with verbose output' is:

un GIT_TRACE=1 GIT_CURL_VERBOSE=1 git ls-remote target
  GIT_TRACE=1 GIT_CURL_VERBOSE=1 git ls-remote target
  shell: /usr/bin/bash -e {0}

I've tried using the PAT locally in terminal and accessing the repo B and it is working, which means PAT is not the problem. Can you please help?
