"cloudflare.ai.toMarkdown.transform" does not work

Confirm this is a Typescript library issue and not an underlying Cloudflare API issue

• This is an issue with the Typescript library

Describe the bug

I pass the correct arguments, but I get an API error.
I think there is a difference in specifications between packages and APIs.

Error: 400 {"errors":[{"message":"Request body is not valid multipart/form-data","code":6005}],"success":false,"result":{},"messages":[]}
    at async Object.handler (D:\Desktop\Projects\aporo-app\.next\dev\server\chunks\ssr\[root-of-the-server]__65d2dc2c._.js:738:24)
    at async (D:\Desktop\Projects\aporo-app\.next\dev\server\chunks\ssr\[root-of-the-server]__65d2dc2c._.js:310:16) {
  status: 400,
  headers: [Object],
  error: [Object],
  errors: [Array]
}
