kindly assist with this error, mobile app keeps loading after converting it using Cordova compiler from workbench but the web app is running well.

error message shows this when I check api link on postman:

{

    "errors": [

        {

            "code": 5002,

            "domain": "%ObjectErrors",

            "error": "ERROR #5002: ObjectScript error: <INVALID OREF>zSetSessionLanguage+7^HSPortal.API.Public.1",

            "id": "ObjectScriptError",

            "params": [

                "<INVALID OREF>zSetSessionLanguage+7^HSPortal.API.Public.1"

            ]

        }

    ],

    "summary": "ERROR #5002: ObjectScript error: <INVALID OREF>zSetSessionLanguage+7^HSPortal.API.Public.1"

}
