Warnings when writing resource to duckdb

When running:

from frictionless import Resource, formats

resource = Resource(
    {
        "name": "reprex",
        "data": [
            ["name", "continent"],
            ["germany", "europe"],
            ["france", "europe"],
            ["spain", "europe"],
        ],
        "schema": {
            "fields": [
                {"name": "name", "type": "string"},
                {"name": "continent", "type": "string"},
            ]
        },
    }
)

conn_string = 'duckdb:///database.db'
resource.write(conn_string, control = formats.SqlControl(table=resource.name))

Although the table get's created in duckdb:

D select * from reprex;
┌─────────┬───────────┐
│  name   │ continent │
│ varchar │  varchar  │
├─────────┼───────────┤
│ germany │ europe    │
│ france  │ europe    │
│ spain   │ europe    │
└─────────┴───────────┘

I get the following warnings:

@fjuniorr I think currently, sqlachemy dialect for DuckDB is not fully finished so I didn't manage to add full test coverage because of issues like https://github.com/Mause/duckdb_engine/issues/289
