Solução Provisória

Currently, the fileName is resolved as follows in src/arcgis/gis/__init__.py:14909

           if data is not None and isinstance(data, (io.StringIO, io.BytesIO)):

               if item_properties is None:

                   item_properties =

               if not "type" in item_properties:

                   item_properties["type"] = self.type

               if not "fileName" in item_properties:

                   fileName = self.name

                   item_properties["fileName"] = fileName

Consider using a random filename, or appending a timestamp to the end of the itemId as a filename.

           if data is not None and isinstance(data, (io.StringIO, io.BytesIO)):

               if item_properties is None:

                   item_properties =

               if not "type" in item_properties:

                   item_properties["type"] = self.type

               if not "fileName" in item_properties:

                   fileName = f"self.name_str(round((datetime.now()).timestamp()))"

                   item_properties["fileName"] = fileName
