How to fix Docker invalid reference format?

I am trying to run docker inside a shell script. This is what my script looks like :-

#!/bin/bash
aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin <account-id>.dkr.ecr.us-east-1.amazonaws.com
IMAGE=$(aws ecr describe-images --repository-name repo --query 'sort_by(imageDetails,& imagePushedAt)[-1].imageTags[0]')
echo $IMAGE
docker pull https://<account-id>.dkr.ecr.us-east-1.amazonaws.com/repo:$IMAGE
docker run -d -p 8080:8080 https://<account-id>.dkr.ecr.us-east-1.amazonaws.com/repo:$IMAGE

But when i run the script, i keep running into

docker: invalid reference format.
See 'docker run --help'.

and i’m not sure what i’m doing wrong. Any help will be appreciated.

    It was failing because the image tag was being returned inside double quotes. Had to get the output in plain text using :-

    aws ecr describe-images --repository-name repo --query 'sort_by(imageDetails,& imagePushedAt)[-1].imageTags[0]' --output text

    From the docs:

    The image name format should be registry/repository[:tag] to pull by tag, or registry/repository[@digest] to pull by digest.

    so for the pull command you should use:

    $ docker pull <account-id>.dkr.ecr.us-east-1.amazonaws.com/repo:$IMAGE

    then for the run command, you should use:

    $ docker run -d -p 8080:8080 <account-id>.dkr.ecr.us-east-1.amazonaws.com/repo:$IMAGE
