    You were completely right, Greg. The user's setting told me that the called code was this one instead of the one I told you in the first post:

     

    fileMetadata = dbxClientV2
      .files()
      .uploadBuilder("/" + dropboxDir + "/" + file.getName())
      .withAutorename(true)
      .withMode(WriteMode.update(oldRevision))
      .withMute(false)
      .uploadAndFinish(fileInputStream);

     

    I did not cleanup everything correctly after the user changed his sync method from another provider to DropBox and did send a wrong oldRevision.

     

    Thanks for the quick feedback and the accurate suggestion.

afritz a. Is that definitely the exact code that is triggering this error? The code shows you using the "overwrite" write mode, but the error mentions the "update" write mode instead. 

 

Also, for reference, the "/Apps" folder name is localized based on the user's account language, but this doesn't affect the API behavior, as app's with the app folder permission don't need to know that app folder root path. The API automatically converts the root path for these apps to be the app folder on the backend.

Thanks for the reply.

I will check this but have to ask the customer about a Setting. I will tell you.

    Thanks. For example, I was able to reproduce this using:

     

    .withMode(WriteMode.update(null))

    The value passed in to WriteMode.update should be the 'rev' value, not null.
