What are you trying to achieve or the steps to reproduce?

I'm using formidable in my Nuxt 3 project, which is deployed on Cloudflare Pages. Within the project, I have an API in the server directory, and in the API I'm parsing a submitted form. When I create a new form variable with const form = formidable({ multiples: true });, the API throws an error and the initialisation fails with the following error. (It's only breaking in the Cloudflare preset, it works okay locally)

What was the result you got?

A promise rejection was handled asynchronously. This warning occurs when attaching a catch handler to a promise after it rejected. (rejection #1)

Now, since I can only see this while running a build preview locally with the Cloudflare preset, the file names are hashed.

What result did you expect?

For the form to be parsed and work as it does locally.

What does the cloudfare preset do ?

@prvashisht Cloudflare Pages? Or Workers?

I think it might be that formidable isn't passed "Node Request", while other environments are having the already standard web api Request. They are slightly different. In some frameworks there are context.request and context.raw.request.

Not sure for Nuxt and presets, not familiar with the Vue ecosystem at all.
