Scripted REST API Azure Webhook for alerts error 500

[AlexanderGreat]

Hi!

I want to run a script to bring all Azure Alerts as incidents on ServiceNow. I've work on a script but I've got this error on Postman:

{
"error": {
"message": "Script Evaluation Exception",
"detail": "Cannot convert {\"status\":\"error\",\"message\":\"Internal Server Error:Cannot convert {\\\"status\\\":\\\"error\\\",\\\"message\\\":\\\"Unauthorized\\\"} to org.mozilla.javascript.ScriptableObject (sys_ws_operation.e1b2d62583e1621010b97629feaad38c.operation_script; line 9)\"} to org.mozilla.javascript.ScriptableObject (sys_ws_operation.e1b2d62583e1621010b97629feaad38c.operation_script; line 53)"
},
"status": "failure"
}

This is the script:

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {

    try {

        // Validate token

        var apiKey = request.queryParams['apiKey'];

        var secret = '********' ; // token

        if (apiKey == secret) {

            response.setStatus(401);

            response.setHeader("Content-Type", "application/json");

            response.setBody(JSON.stringify({ status: "error", message: "Unauthorized" }));

            return;

        }

        // Parse request body

        var rawBody = request.body.data;

        var payload = (typeof rawBody === "string") ? JSON.parse(rawBody) : rawBody;

        if (!payload || !payload.data || !payload.data.essentials) {

            response.setStatus(400);

            response.setHeader("Content-Type", "application/json");

            response.setBody(JSON.stringify({ status: "error", message: "Missing essentials in payload" }));

            return;

        }

        var e = payload.data.essentials;

        // Create incident

        var gr = new GlideRecord("incident");

        gr.initialize();

        gr.short_description = "Azure Alert: " + e.alertRule;

        gr.description =

            "Severity: " + e.severity + "\n" +

            "Signal Type: " + e.signalType + "\n" +

            "Condition: " + e.monitorCondition + "\n" +

            "Fired At: " + e.firedDateTime + "\n\n" +

            "Description:\n" + e.description;

        var sysId = gr.insert();

        // Return success to Azure

        response.setStatus(200);

        response.setHeader("Content-Type", "application/json");

        response.setBody(JSON.stringify({

            status: "success",

            message: "Incident created",

            sys_id: sysId

        }));

    } catch (err) {

        gs.error("Azure Webhook Script Error: " + err.message);

        response.setStatus(500);

        response.setHeader("Content-Type", "application/json");

        response.setBody(JSON.stringify({

            status: "error",

            message: "Internal Server Error:" + err.message

        }));

    }

})(request, response);

This is the POST: https://dev186149.service-now.com/api/1731864/azure_alerts/create_incident?apiKey=************

Can someone help me on this?
