Hi,

I've been encountering a persistent "Generic user error" when attempting to send messages using the WhatsApp Messaging API with templates. This issue has been occurring for the past 8 days. Previously, the template sending functionality was working without problems. Only this is working for the test template provide by facebook i.e. "hello_world"

Details:

API Endpoint: (https://graph.facebook.com/v19.0/{{phone_number_id}}/messages)

Payload:

{
    "messaging_product": "whatsapp",
    "to": "+919870970092",
    "type": "template",
    "template": {
        "name": "product_public_course_launched",
        "language": {
            "code": "en_US"
        },
        "components": [
            {
                "type": "header",
                "parameters": [
                    {
                        "type": "image",
                        "image": {
                            "link": "https://gcubelmsqc.gc-solutions.net/Product/Control/ThumbnailGenerator.aspx?LoggedIn=0&Canvas=true&ImageWidth=198&ImageHeight=132&directLink=true&ImageFile=/Content/Specific/Images/SmartContent.jpg"
                        },
                        "text": null
                    }
                ]
            },
            {
                "type": "body",
                "parameters": [
                    {
                        "type": "text",
                        "image": null,
                        "text": "Vineet g2181"
                    },
                    {
                        "type": "text",
                        "image": null,
                        "text": "1 April smart content_All"
                    },
                    {
                        "type": "text",
                        "image": null,
                        "text": "NA"
                    },
                    {
                        "type": "text",
                        "image": null,
                        "text": "https://gcubelmsqc.gc-solutions.net/product/learner/#/deeplink?metadata=Zr2WplddJX3U2tDG9egQBz0yxVN9pSoSA%2bsibKV%2fWd2bcjoSMkEwQnG%2fByAQ8vaBtxQqmKNVVW2rLW38DZBdHpILqD0n32q7I6DGQFGoS6TVpl%2bTYnvV1e2kkNhnxAhqmWgWyRz69RQ%3d"
                    }
                ]
            }
        ]
    }
}

Error Message:

{
    "error": {
        "message": "(#135000) Generic user error",
        "type": "OAuthException",
        "code": 135000,
        "error_data": {
            "messaging_product": "whatsapp",
            "details": "Generic user error"
        },
        "fbtrace_id": "ABCrXcTBH-7Q-wCMEBEgh3K"
    }
}

Steps taken: - Double check template Formatting. - Double check the API keys. - Double check the URL and Phone number Id. - Already tried with new templated. - Change access token and retry

This issue is causing significant disruption to my workflow. I would greatly appreciate any urgent assistance or insights from the community to resolve this "Generic user error" and get my WhatsApp template messaging back on track.
