Aws Ssm Policy Doesn't Work Like the Documentation

I tried to provide a policy following the samples here:

But, I keep getting a warning and it does not work.

These are all I tried so far:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowStartSessionExceptProd",
            "Effect": "Allow",
            "Action": [
                "ssm:StartSession"
            ],
            "Resource": "*",
            "Condition": {
                "StringNotLike": {
                    "ssm:resourceTag/environment": [
                        "prod",
                        "Prod"
                    ]
                }
            }
        }
    ]
}

Or

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowStartSessionExceptProd",
            "Effect": "Allow",
            "Action": [
                "ssm:StartSession"
            ],
            "Resource": "*",
            "Condition": {
                "StringEquals": {
                    "arn:aws:ec2:*:*:instance": [
                        "i-myInstanceId1",
                        "i-myInstanceId2"
                    ]
                }
            }
        }
    ]
}

Or even I tried to use more resource-based conditions.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowStartSessionExceptProd",
            "Effect": "Allow",
            "Action": [
                "ssm:StartSession"
            ],
            "Resource": "*",
            "Condition": {
                "StringNotLike": {
                    "ssm:resourceTag/environment": [
                        "prod",
                        "Prod"
                    ],
                    "arn:aws:ec2:*:*:resourceTag/environment": [
                        "prod",
                        "Prod"
                    ],
                    "ec2:resourceTag/environment": [
                        "prod",
                        "Prod"
                    ]
                }
            }
        }
    ]
}

In general, all I want to do is allow access to start session in SSM on servers which are not prod servers. My EC2 prod servers all have a tag environment:prod

I get an error message on each condition which doesn't work: There are no actions in your policy that support this condition key.

Example: ec2:resourceTag /environment (StringNotLike prod and Prod) There are no actions in your policy that support this condition key.

I appreciate any help.
