Hi Greg, thank you for the comment.

I tried with `cors: false`, but it also failed in the same DNS error. This is the request I am using.

var params = {...};
var headers = {
  'Content-Type': 'application/json',
  'api-key': '...',
};
var settings = {
  url: 'https://....openai.azure.com/openai/...,
  contentType: 'application/json',
  secure: true,
  cors: false,
  type: 'POST',
  headers: headers,
  data: JSON.stringify(params),
};
return client.request(settings)...

The "api-key" param is `{{setting.api_key}}` (api_key param is in the parameters of manifest.json), but I tried both with the raw value and `{{setting.api_key}}`.

If I remove the line "cors: false" (means use only secure:true), this failed in DNS error.

If I remove the line "secure: true" and use api-key with raw value (means use only cors:false), this request works.

Can you find something?
