Next.js Edge Runtime

[FynniX]

Hello,
when I want to use this inside next.js in the edge runtime, then I get a error.

 [Error: Bad Request] {
  status: 400,
  message: 'Bad Request',
  details: 'Boundary not found for multipart/form-data request',
  type: 'MailgunAPIError'
}

The error happens when I want to use the FormData from next.js edge runtime api.

Hello @FynniX
This happens due to the limitations of Next.js "Edge runtime" and the usage of Axios under the hood of the Mailgun.js
With this combination (Axios + Edge runtime), the "Boundary" header for multipart/form-data is never set.

I will work on this in the near future.

As for now I can suggest few options on how to avoid the issue:

• Move the usage of Mailgun from the middleware to the route resolver.
• Use fetch to access the Mailgun API directly.
