[Suryadhulipudi]

Hi, Can somebody point me, what i am missing here. Thanks in advance.

Here is my yaml file

name: trigger jenkins job
on: 
  pull_request:
    branches: [ master ]

jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
    - name: trigger single Job
      uses: appleboy/jenkins-action@master
      with:
        url: "http://10.0.0.1:8080"
        user: "jenkins"
        token: ${{ secrets.jenkins }}
        job: "abc"

make sure secrets.jenkins is available for your repo. Check Github secret configuration.
