--output text flag is giving different results when set

[j0rzsh]

Describe the bug

So the issue I have encountered is this:

aws ecr describe-images --repository-name my-repo --query "sort_by(imageDetails,& imagePushedAt)[-1]" --no-cli-pager
Output:

{
    "registryId": "xxxxxxxxxx",
    "repositoryName": "my-repo",
    "imageDigest": "sha256:b10aa8e713a0e9bf2e8ed2b9b133fd4a88e8f5f1de4ef68c14691f977bd7c912",
    "imageTags": [
        "18122024T1715"
    ],
    "imageSizeInBytes": 105261770,
    "imagePushedAt": "2024-12-18T18:17:18.998000+01:00",
    "imageManifestMediaType": "application/vnd.docker.distribution.manifest.v2+json",
    "artifactMediaType": "application/vnd.docker.container.image.v1+json",
    "lastRecordedPullTime": "2024-12-18T18:17:20.300000+01:00"
}

aws ecr describe-images --repository-name my-repo --query "sort_by(imageDetails,& imagePushedAt)[-1]" --output text --no-cli-pager

Output:

application/vnd.docker.container.image.v1+json	sha256:65cd04e822b8a3e576e90f68a07b7a9ade8eaca40662319a4074208640e17ebc	application/vnd.docker.distribution.manifest.v2+json	2024-12-18T18:00:22.553000+01:00	105261604	2024-12-18T18:00:23.862000+01:00	xxxxxxxxxx	my-repo

So the same command with the same query is returning two different responses only for setting the --output flag to text. I am not sure if this is the intended behaviour but I don't really understand the reason.

aws --version
Output:
aws-cli/2.22.14 Python/3.12.6 Darwin/23.6.0 exe/x86_64

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Return same amount of items and same information when --output test flag is set and when it is not.

Current Behavior

When no --output flag is set, or when is set to json, only one result is appearing. When --output is set to text, two results are appearing.

Reproduction Steps

We haven't encountered this issue ever and we have been using the exact same command for years. Only difference I see now is that the two images where pushed with only 17 minutes apart from each other.

Possible Solution

No response

Additional Information/Context

CLI version used

This looks like it might be a duplicate of this issue I raised a short while ago: #8998
Despite the documentation, it feels like misleading behaviour.

[j0rzsh]

Hmm that looks like the same cause, yes. Many thanks for bringing that up I didnt saw it.

I would also add some bit of information after more testing we did. This only is appearing in the ECR repository in which we are using the docker labels in the images. This is a new development we are doing but we didn't think that should change that awscli response 🤔

We ended up doing the same as I can see now in your issue, in this comment.

Many thanks, I will close the issue because as I can see it is not intended to be changed, even though it is pretty confusing behaviour.
