Serverless app invokeTemplate always returns 403: URL not allowed

App Platform

I created a v2.3 serverless app that calls an external site and it works perfectly when run locally (fdk run) but when installed, it logs:

{ status: 403, headers: {}, response: ‘URL not allowed’, errorSource: ‘APP’, attempts: 1 }

The target URL is open to the internet (I have tried both public sites like webhook.site and my own domain URLs)

Any help appreciated.

Hi @Mark_Dedlow

Can you check your request URL and try the hardcoded URL in the request?

I do have it hardcoded:

{
“postTimeSheet”: {
“schema”: {
“protocol”: “https”,
“method”: “POST”,
“host”: “webhook.site”,
“path”: “/5c1b5b05-aca6-4270-883e-bb16a9f5e8b3”,
“headers”: {
“Content-Type”: “application/json”
}
}
}
}

Hi @Mark_Dedlow

Can you try this

 "postTimeSheet": {
    "schema": {
      "method": "POST",
      "host": "webhook.site",
      "path": "/5c1b5b05-aca6-4270-883e-bb16a9f5e8b3",
      "headers": {
        "Content-Type": "application/json"
      }
    }
  }

That’s the same but without protocol. That has same error.

Hey @Mark_Dedlow

Can you try the same request in Postman? so that we can find the issue
