Does not enable checkbox when using

Hi,

i have a python script which creates workspace, datastore and a layer in a dockerized geoserver when the container is up’ed with docker compose.

The problem is, i want to enable this checkbox and have following RestAPI Command. It creates the datastore but does not check the box.

    datastore_data = f"""
    <dataStore>
        <name>{datastore_name}</name>
        <connectionParameters>
            <host>database</host>
            <port>5432</port>
            <database>xxx}</database>
            <schema>yyy</schema>
            <user>zzz</user>
            <passwd>123</passwd>
            <dbtype>postgis</dbtype>
            <exposePrimaryKeys>true</exposePrimaryKeys>
        </connectionParameters>
    </dataStore>
    """

Somebody has an idea, why its not working. The Documentation is not very good and i cant find answers online.

Cheers
