build process in github actions completed with exit code 2 - github-actions

Question

When I was trying to run the git action to build a docker image, got the following error. Any insight into what went wrong? Thanks!
Here is the workflow yaml:
name: Python application
on:
push:
paths:
- 'python/*'
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v1
- name: Set up Python 3.7
uses: actions/setup-python#v1
with:
python-version: 3.7
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r ./python/requirements.txt
- name: Build & Push Image
run: |
cd ./python
echo "${{ secrets.DOCKERPW }}" | docker login -u "[your dockerhub login here]" --password-stdin
docker image build -t [your dockerhub username here]/gitops:hellov1.0 .
docker push [your docker hub username here]/gitops:hellov1.0
the error message in the log:

cd ./python
