Docker push doesn't work even docker login succeeded during AWS CodePipeline Build stage

Hello,

I'm preparing CI/CD using AWS CodePipeline. Unfortunatelly I have an error during build stage. Below there is content of my buildspec.yml file, where:

AWS_DEFAULT_REGION = eu-central-1

CONTAINER_NAME=cicd-1-app

REPOSITORY_URI = <ACCOUNT_ID>.dkr.ecr.eu-central-1.amazonaws.com/cicd-1-app

version: 0.2
phases:
  install:
    runtime-versions:
      java: corretto11
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - aws --version
      - TAG="$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | head -c 8)"
      - IMAGE_URI=${REPOSITORY_URI}:${TAG}
  build:
    commands:
      - echo Build started on `date`
      - echo $IMAGE_URI
      - mvn clean package -Ddockerfile.skip
      - docker build --tag $IMAGE_URI .
  post_build:
    commands:
      - printenv
      - echo Build completed on `date`
      - echo $(docker images)
      - echo Pushing docker image
      - aws ecr get-login-password --region $AWS_DEFAULT_REGION | docker login --username AWS --password-stdin <ACCOUNT_ID>.dkr.ecr.eu-central-1.amazonaws.com
      - docker push $IMAGE_URI
      - echo push completed
      - printf '[{"name":"%s","imageUri":"%s"}]' $CONTAINER_NAME $IMAGE_URI > imagedefinitions.json
artifacts:
  files:
    - imagedefinitions.json

I got error:

Even docker logged in successfully there is "no basic auth credentials" error. Do you know what could be a problem?

Best regards.
