Custom Distributor Packages "failed to download installation package"

Hi all,

I have been playing with SSM Distributor packages in the hopes of managing various agents across the fleet. I have been able to build / compile a couple of different packages successfully.

Unfortunately when I attempt to deploy them to instances, as per the doco, ie;

aws ssm send-command --document-name "AWS-ConfigureAWSPackage" --instance-ids "i-abcdefghijk" --parameters '{"action":["Install"],"installationType":["Uninstall and reinstall"],"name":["CustomPackage"]}'

I am receiving the following error;

aws ssm get-command-invocation --command-id 1234567-8910-1112-1314-abcdefghi --instance-id i-abcdefghijk
{
    "CommandId": "1234567-8910-1112-1314-abcdefghi",
    "InstanceId": "i-abcdefghijk",
    "Comment": "",

    "ExecutionEndDateTime": "2020-04-01T04:33:04.700Z",
    "Status": "Failed",
    "StatusDetails": "Failed",

    "StandardOutputUrl": "",
    "StandardErrorContent": "failed to download installation package reliably, , Get : unsupported protocol scheme \"\"\nfailed to download installation package reliably, , Get : unsupported protocol scheme \"\"\nfailed to download installation package reliably, , Get : unsupported protocol scheme \"\"\n",
    "StandardErrorUrl": "",
    "CloudWatchOutputConfig": {
        "CloudWatchLogGroupName": "",
        "CloudWatchOutputEnabled": false
    }
}

The error occurs on all custom packages for both windows and linux instances. Packages published by AWS still continue to deploy successfully.

Has anyone written any packages and run into similar errors?

RESOLVED - For anyone interested, even though the documentation says otherwise, if you refer to your custom package by its arn rather than the short name you will no longer have the issue. ie,

aws ssm send-command --document-name "AWS-ConfigureAWSPackage" --instance-ids "i-abcdefghijk" --parameters '{"action":["Install"],"installationType":["Uninstall and reinstall"],"name":["arn:aws:ssm:ap-southeast-2:123456789101:document/CustomPackage"]}'
