**Expected behavior**
should work upload image to ecr

**Screenshots**


**Your Environment**
Azure Devops with latest version

**Additional context**

Start by reproducing the Amazon ECR Push task in Azure DevOps with the Docker image and command shown in the log, then inspect the task entry point that invokes Docker push. Compare the HTTP 403 response handling with the reported empty body. Done means the task reports a useful failure or successfully pushes the image to ECR.
