Description

I am trying to use the wbsetclaim . I am getting the following error from the API. I am trying to use this API for the first time. It would be great if someone could take a look at the error and help me.

{
    "error": {
        "code": "internal_api_error_Deserializers\\Exceptions\\DeserializationException",
        "info": "[5b3b0826-e761-43e6-b577-1afa39901a47] Caught exception of type Deserializers\\Exceptions\\DeserializationException",
        "errorclass": "Deserializers\\Exceptions\\DeserializationException"
    },
    "servedby": "mw1314"
}

This is the claim object that I have:

While this error should definitely be investigated, note that P2096 should be a qualifier, not a reference.

Thanks, @matej_suchanek. That was indeed the cause of the error.

I am now able to call the API successfully. For reference, this is the claim that I am using now.
