Found an error in the above file in

def publish_req_chunked(self, datasource_item, connection_credentials=None):
xml_request = self._generate_xml(datasource_item, connection_credentials, connections)
parts = {'request_payload': ('', xml_request, 'text/xml')}
return _add_multipart(parts)

which is related to uploading larger tde files and I was getting failures when I tried to upload a tde to the server. Tracing the calling method it is missing "connections"

I modified the method to:

def publish_req_chunked(self, datasource_item, connection_credentials=None, connections=None):
xml_request = self._generate_xml(datasource_item, connection_credentials, connections)
parts = {'request_payload': ('', xml_request, 'text/xml')}
return _add_multipart(parts)

and I was able to use the library to upload my tde file to the server.
