I want to Create a DefinitionValue based on this documentation.

But this doesn't work:

https://graph.microsoft.com/beta/deviceManagement/groupPolicyConfigurations/{groupPolicyConfigurationID}/definitionValues

{
    "@odata.type": "#microsoft.graph.groupPolicyDefinitionValue",
    "enabled": true,
    "configurationType": "policy",
    "definition@odata.bind": "https://graph.microsoft.com/beta/deviceManagement/groupPolicyDefinitions('{groupPolicyDefinitionID}')"
}

Does anyone know, how I'm able to create a Definition Value?

Edit: Thats the Error I get:

    "error": {
        "code": "ResourceNotFound",
        "message": "{  \"_version\": 3,  \"Message\": \"An error has occurred - Operation ID (for customer support): 00000000-0000-0000-0000-000000000000 - Activity ID: dae9a903-29fe-6dd7-bb27-e02f375f816a - Url: https://fef.msub06.manage.microsoft.com/GroupPolicy/GroupPolicyAdminService/b15c97ad-ffff-4805-0302-032414203983/deviceManagement/groupPolicyConfigurations%28%276c39baa2-f47a-4d9f-a7cb-327ea6b60fc0%27%29/definitionValues?api-version=5018-11-06\",  \"CustomApiErrorPhrase\": \"\",  \"RetryAfter\": null,  \"ErrorSourceService\": \"\",  \"HttpHeaders\": \"{}\"}",
