Support: Aptly API Publishing and batch options

[cloudy-dayzz]

Hello!
I am struggling to publish to s3 from aptly API. I believe this is due to incorrect signingOptions in my json.

This is when calling the API from a remote location

My setup is as below.

A local repo named "test", which publishes to an s3 repository.

I am able to successfully add files to the repository, doing the following :

curl -sSF file=@${DEB} ${APTLY_BASE_URL}/api/files/${CI_COMMIT_TAG}; ✅
curl -sSX POST ${APTLY_BASE_URL}/api/repos/test/file/${CI_COMMIT_TAG}; ✅
curl -X POST -H 'Content-Type: application/json' --data @../templates/upload_to_aptly.json ${APTLY_BASE_URL}/api/publish ❌

My JSON looks like so (Sanitized):

    "Sources": [
        {"Name": "test"}
        ],
        "Architectures": ["amd64"],
        "Distribution": "test",
        "Storage": "s3",
        "Signing": {
        "Batch": "true",
        "PassPhrase": "XXXXX"
        }
    }

I receive the following error message:
{error":"unable to publish: unable to detached sign file: exit status 2"}

What I believe is happening is that the publish API is not respecting my Signing options, as if I keep watch on the aptly server, it brings up the prompt to enter my passphrase.

Please can you let me know where i'm going wrong?!

Thanks.
