Error: buildx failed with: ERROR: invalid tag "***/e2bdy:": invalid reference format

Question

I'm using github action to build&push docker image, but it failed with err.

errors screenshots

buildx failed with: ERROR: invalid tag "***/e2bdy:": invalid reference format

Is there anything wrong with my action.yml ? Local build is successful.

name: e2bdy docker
on:
  workflow_dispatch:
  push:
    branches:
      - main
    paths:
      - version.py
      - .github/workflows/build.yml
      - requirements.txt
      - dockerfile

        run: |
          app_version=$(cat version.py |sed -ne "s/APP_VERSION\s=\s'v\(.*\)'/\1/gp")
          echo "app_version=$app_version" >> $GITHUB_ENV

        with:

          password: ${{ secrets.DOCKER_PASSWORD }}

      - name: Build Image
        uses: docker/build-push-action@v2
        with:
          context: docker
          file: dockerfile
          build-args: |
            GITHUB_TOKEN=${{ secrets.RELEASE_TOKEN }}
          platforms: |
            linux/amd64
            linux/arm64
          push: true
          tags: |
            musnows/e2bdy:latest
            musnows/e2bdy:${{ env.app_version }}

dockerfile

FROM python:3.11.2
COPY requirements.txt requirements.txt
RUN pip install --no-cache-dir -r requirements.txt

ENV LANG="C.UTF-8" \
    TZ="Asia/Shanghai" \
    PGID=0 \
    PUID=0 \
    BDY_SECRET_KEY="" \
    BDY_APP_KEY="" \
    BDY_APP_NAME="e2bdy" \
    ENCRYPT_UPLOAD=1 \
    SYNC_INTERVAL=600

WORKDIR /app

COPY . /app/
COPY ./config /app/config

VOLUME [ "/app/config" ]

CMD [ "python","main.py" ]

github repo：https://github.com/musnows/encrypt2bdy/tree/main

At first,I used ${{ secrets.DOCKER_USERNAME }}/e2bdy:latest for image name, it failed with this err.So I tryed to use my username instead of action secrets,but it still failed in build docker image

this yaml works

name: Docker Image CI
#触发器设置
on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

#项目任务，任务之间可以并行调度
jobs:
  build:
  #选择云端运行的环境
    runs-on: ubuntu-latest
    steps:
    #uses代表使用一个模块，此处使用的是checkout模块，将github项目文件导入到当前环境中
    - uses: actions/checkout@v3
    #使用with跟在后面来为前面的模块输入参数
      with:
        submodules: 'true'
    - name: Set up QEMU
      uses: docker/setup-qemu-action@v2
    - name: Set up Docker Buildx
      uses: docker/setup-buildx-action@v2
    - name: Login to DockerHub
      uses: docker/login-action@v2
      with:
     # 这里用到了github的secrets功能，避免账户和密码随仓库泄露
       username: ${{ secrets.DOCKER_USERNAME }}
       password: ${{ secrets.DOCKER_TOKEN }}
    - name: Build and push
      # 导入这个模块来完成自动编译和推送
      uses: docker/build-push-action@v3
      with:
          context: .
          push: true
          #在这里通过加入需要编译的平台和前面配好的QEMU，buildx来达到多平台编译
          platforms: linux/amd64,linux/arm64,linux/arm
          #指定用户/仓库名
          tags: musnows/e2bdy:latest
    - name: Docker Hub Description
      # 这里是通过md文件自动生成dockerhub描述的模块，也可以不需要
      uses: peter-evans/dockerhub-description@v3
      with:
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}

The old one fiailed because I didn't set version.py correctly

# the right one
APP_VERSION = 'v0.1.0'
# err!
APP_VERSION = '0.1.0'

Now I'm using this yaml,which cloud push docker images with latest & version in version.py

name: Docker Image CI
#触发器设置
on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

# 项目任务，任务之间可以并行调度
jobs:
  build:
  # 选择云端运行的环境
    runs-on: ubuntu-latest
    steps:
    #u ses代表使用一个模块，此处使用的是checkout模块，将github项目文件导入到当前环境中
    - uses: actions/checkout@v3
    # 使用with跟在后面来为前面的模块输入参数
      with:
        submodules: 'true'
    - name: Set up QEMU
      uses: docker/setup-qemu-action@v2
    - name: Set up Docker Buildx

    - name: Login to DockerHub

      run: |
        app_version=$(cat version.py |sed -ne "s/APP_VERSION\s=\s'v\(.*\)'/\1/gp")
        echo "app_version=$app_version" >> $GITHUB_ENV
