GitHub CI error parsing HTTP 404 response body when pushing the image

Question

Coming from this issue

I am using GitHub Actions for Gradle project with this given steps:

name: Java CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1
      - name: Set up JDK 13
        uses: actions/setup-java@v1
        with:
          java-version: 13

      - run: ./gradlew bootJar

      - name: Login to Github regestry
        run: docker login docker.pkg.github.com -u xxxxx -p xxxxx

      - name: Build the Docker image
        run: docker build . -t docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.$GITHUB_REF


      - name: Push the image to github
        run: docker push docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.$GITHUB_REF

At the last step I get this error:

The push refers to repository [docker.pkg.github.com/sulimanlab/realtime-chat/realtimechat-snapshot-0.refs/heads/master]

This seems like an issue with docker, not github actions. See this issue — smac89
I solved it actually, many thanks man stackoverflow.com/a/58938666/10420300 — suliman
Nice one. I was just about to post something I read about github packages. It says the way to push is to use the syntax docker push docker.pkg.github.com/OWNER/REPOSITORY/IMAGE_NAME:VERSION, then below that it says, Note: You must push your image using IMAGE_NAME:VERSION and not using IMAGE_NAME:SHA. If this works for you, I guess it works then which is good — smac89

actually I was using the wrong environment variable to tag my images.

I used $GITHUB_REF what I should use $GITHUB_SHA
