Uploading multiple file with session Typescript

Uploading multiple file with session Typescript

Explorer | Level 4


I'm facing an issue with the UploadSessionFinishBatch method with TypeScript.

I'm having this error :

Error in call to API function \"files/upload_session/finish_batch\": request body: entries: unknown field 'contents

It seems like the "contents" parameter is not supposed to be here and makes the call crash. But in TypeScript the contents is required.

In some example I found on the web I've never seen the contents parameter. Is it a problem of type due to TypeScript SDK ? Or there is something I miss ?

Here is the code I use

const finishUploadBatchArg: DropboxTypes.files.UploadSessionFinishBatchArg = {
      entries: [],

// For each file I do : 
const response = await this.dropBox.filesUploadSessionStart(uploadSessionStartArg)
        sessionId = response.session_id
        const cursor: DropboxTypes.files.UploadSessionCursor = {
          contents: file,
          session_id: sessionId,
        const commitInfo: DropboxTypes.files.CommitInfo = {
          contents: file,
          path: filePath,
          autorename: true,

        const finishSessionArg = {
          contents : file, //This one is unknown from what I understand of the error I get
          cursor: cursor,
          commit: commitInfo,
//Then I call the finish batch method : 
const response: DropboxTypes.files.UploadSessionFinishBatchLaunch = await this.dropBox.filesUploadSessionFinishBatch(finishUploadBatchArg)

By the way all the session start goes well.

Can you please help me on this ?

This appears to be a duplicate of this thread, so I'll close it and follow up with you there.
