Unable to Create Webhooks via API in Forge App

[PgM Innovations]

I'm having trouble creating webhooks using the Jira REST API within my Forge app. Here is the request I'm making:

const webhookPayload = {

    name: "Sprint Updated Webhook",

    enabled: true,

    description: "Webhook for getting sprint updates",

    url: webhookUrl,

    events: [

        "jira:sprint_created",

        "jira:sprint_updated",

        "jira:sprint_deleted"

    ],

    excludeBody: false,

    secret: null,

    filters: {"issue-related-events-section": ""},

    lastUpdatedDisplayName: "",

    lastUpdatedUse: ""

};

const response = await api.asApp().requestJira(route`/rest/webhooks/1.0/webhook`, {

    method: 'POST',

    body: JSON.stringify(webhookPayload),

    headers: {

        'Content-Type': 'application/json'

    }

});

Despite this, I'm not seeing the webhook being created in my Jira instance. Here are some additional details:

• The webhookUrl is correctly set to the URL that handles the webhook events.
• I have the necessary permissions in my manifest.yml
  permissions:
•   scopes:
•     - read:jira-work
•     - write:jira-work
•     - manage:jira-webhook
