AWS Athena query only returns a single column in results when using iam role

Hello. I've encountered an issue that might be related to not enough iam permissions, but I can't find any documentation about what policies I could be missing.

My IAM Role has the following managed policies:

arn:aws:iam::aws:policy/service-role/AWSQuicksightAthenaAccess
arn:aws:iam::aws:policy/AmazonS3FullAccess
arn:aws:iam::aws:policy/AmazonAthenaFullAccess

I have the iam role configured and working in my .aws/config file and when I execute an athena query like this:

aws athena start-query-execution \                                                    
    --query-string "SELECT * FROM my_schema.my_table WHERE dt='2022-08-17-10'" \
--query-execution-context Database=default,Catalog=awsdatacatalog \
--result-configuration OutputLocation=s3://aws-athena-query-results-my-athena-results123344-us-east-1/ \
--profile my-athena-role

I get a result like the following:

{
    "ResultSet": {
        "Rows": [
            {
                "Data": [
                    {
                        "VarCharValue": "dt"
                    }
                ]
            },
            {
                "Data": [
                    {
                        "VarCharValue": "2022-08-17-10"
                    }
                ]
            },
            {
                "Data": [
                    {
                        "VarCharValue": "2022-08-17-10"
                    }
                ]
            },
            {
                "Data": [
                    {
                        "VarCharValue": "2022-08-17-10"
                    }
                ]
            },
            {
                "Data": [
                    {
                        "VarCharValue": "2022-08-17-10"
                    }
                ]
            },
...

As you can see, only the column dt is returned in the resultset. That table contains many more columns.

Running the same query without the IAM Role, with my default account that has full access to all resources produces the desired results.

So it seems it's related to the limited permissions, but I can't figure out which ones I'm missing in my IAM Role.

Thanks in advanced.
