I wrote a python project that automates tasks and makes use of the smartsheet api but when I package this project into an executable with nuitka I get the error: ImportError! Could not load api or model class Search Error: 'str' object has no attribute 'search_sheet' this is the piece of code that throws this error from smartsheet import smartsheet ... smart = smartsheet.Smartsheet("api key",proxies=proxies) # Create a Smartsheet client response = smart.errors_as_exceptions(True) # Call the list_sheets() function and store the response object NonFoundSerialNumbers="" try: SerialNumbers=SerialNumbers.split(" ") for search in SerialNumbers: response=smart.Search.search_sheet(sheetID,search) if len(response.results)==0: NonFoundSerialNumbers=NonFoundSerialNumbers+"\n"+search etc ... This error makes me believe that the smartsheet client is not being created due to an import error of some sort when packaging the project.
