#373 is similar to this Issue, but I believe the cause is different.

Bump this - facing the same issue

Since the library is not updated and probably won't be, would there be any other simple implementation based on its dependencies?

Using busboy directly, what would it look like...?

Hey @LucasBonafe - I was able to achieve this by using the parse-multipart. To do this, you will have to read the raw body of the request as a buffer stream and make sure you extract the boundaries of the form-data using multipart. The following is an example

import * as multipart from 'parse-multipart';

# in your function

const rawBody = await request.body.getReader().read();
const contentType = request.headers.get('content-type');
const boundary = multipart.getBoundary(contentType);

if(boundary) {
try {
    let files: Form[] = multipart.Parse(Buffer.from(rawBody.value), boundary);
    # Print out all the files in the form-data body
    console.log(files)
    # Print out the content of the files
      files.map(file => context.log(file.data.toString()));
} catch (error) {
  return {status: 400, body: error};
}
