Discussion on: Set up CI/CD for containerized React App using Docker, AWS CodeBuild, AWS ECS, AWS CodePipeline & Github

I have just setup another pipeline. I made sure I followed your steps exactly as it is. And I still have the same error.

version: 0.2
phases:
install:
runtime-versions:
docker: 19
pre_build:
commands:
- $(aws ecr get-login --region $AWS_DEFAULT_REGION --no-include-email)
- REPOSITORY_URI=780571656781.dkr.ecr.us-east-2.amazonaws.com/spurts-app
- COMMIT_HASH=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
- IMAGE_TAG=${COMMIT_HASH:=latest}
build:
commands:
- docker build -t $REPOSITORY_URI:latest -f Dockerfile .
- docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$IMAGE_TAG
post_build:
commands:
- docker push $REPOSITORY_URI:latest
- docker push $REPOSITORY_URI:$IMAGE_TAG
- printf '[{"name":"spurts-container","imageUri":"%s"}]' $REPOSITORY_URI:$IMAGE_TAG > imagedefinitions.json
artifacts:
files: imagedefinitions.json

This is my Buildspec file
