The requested scope is invalid, unknown, or malformed

Describe the problem/error/question

Hey there, when using the HTTP Request node to make a call on my OCR API, i get an error.

It works fine using the API swagger from Open API.

It also works fine using Insomnia Request Handler.

I’m using the exact same auth configuration on n8n, but it doesn’t work.

What is the error message (if any)?

{
  "errorMessage": "The requested scope is invalid, unknown, or malformed.",
  "errorDetails": {
    "rawErrorMessage": [
      "The requested scope is invalid, unknown, or malformed."
    ],
    "httpCode": "EAUTH"
  },

    "binaryDataMode": "default",
    "stackTrace": [

      "    at Object.execute (/home/mat/documents/n8n/packages/nodes-base/nodes/HttpRequest/V3/HttpRequestV3.node.ts:1894:15)",

hello @Gentleman9914

OAuth requires you to use a scope parameter that is not set in your credentials. Check the docs for the service you are trying to connect to

Hey there, I know but the API I’m trying to use is my own, that we host on our infrastructure.

It works fine in Insomnia without any scope :

I don’t really know what else I can do, maybe try to roll up n8n locally and debug on my computer.

[Gentleman9914]

I’ve just had success adding this scope :

openid profile email

Don’t know exactly why was it required as I don’t use any on the swagger nor on my Insomnia HTTP client for the exact same request but anyway I can keep going forward now.
