Are you sure that your file content is of type string | Blob | Buffer?

I have the same problem..
with String I get your error (source.on is not a function) and if I use Buffer I get an HTTP 400 Error with Error Body: {"exception":"invalidArgument","message":"Invalid form encoding!"}

Any ideas?

The problem could be the native fetch implementation in node 18. You can try with node 16 or replace the global fetch with the fetch implemantation used in cmis.

install node-fetch:
npm install node-fetch

replace native fetch:

import fetch, {
  Blob,
  blobFrom,
  blobFromSync,
  File,
  fileFrom,
  fileFromSync,
  FormData,
  Headers,
  Request,
  Response,
}
from 'node-fetch';

if (!globalThis.fetch) {
  globalThis.fetch = fetch
  globalThis.Headers = Headers
  globalThis.Request = Request
  globalThis.Response = Response
}
