File

What problem was encountered?

I get the following error when I attempt to initialize the FileService class. The following was working fine and then without notice it stopped working and started giving the following error:

Client-Request-ID=bc4ba635-7aef-11e8-be6a-000d3a319612 Retry policy did not allow for a retry: Server-Timestamp=Thu, 28 Jun 2018 16:24:31 GMT, Server-Request-ID=7ee390c2-c01a-0081-0efc-0e9221000000, HTTP status code=404, Exception=The specified resource does not exist.ErrorCode: ResourceNotFoundResourceNotFoundThe specified resource does not exist.RequestId:7ee390c2-c01a-0081-0efc-0e9221000000Time:2018-06-28T16:24:31.0526845Z.

I have verified that I am able to create a share and upload a file through the web interface without issue. Any help would be greatly appreciated

Hi @ttelfer, thanks for reaching out.

To clarify, initializing the FileService class cannot produce any such error, because it does not make any network request.

Thanks for providing your code. I see a potential problem in this part:

def upload_files(self,
                                file_paths: List[str]):
        for f in file_paths:
             self.file_service.create_file_from_path(
                        SHARE_NAME,
                        None,
                        filename,
                        f,
                        content_settings=ContentSettings(content_type=CONTENT_TYPE[file_extension])
             )

        return

Where is filename defined? Did you miss a few lines when copy/pasting the code? The error 404 is most likely thrown in your retrieve_file_in_directory method. Please double check that the file you are getting actually exists.

Hi @ttelfer, I'm closing this for now due to lack of response. Please feel free to provide more information if you think there's an issue related to the SDK.
