I used this code to run the app from python but it giving me errors: prodigy.serve("textcat.manual", "esg\_tagged\_test", "en\_core\_web\_lg", "./ESG\_classifications\_analystA.jsonl", None, ["ESG", "Not\_ESG", "Confused"], True, None, port=9000) it's giving the following error: \lib\site-packages\prodigy\recipes\textcat.py in manual(dataset, spacy\_model, source, api, loader, label, exclusive, exclude) 127 log("RECIPE: Loaded model {}".format(spacy\_model)) 128 labels = label --\> 129 has\_options = len(labels) \> 1 130 log("RECIPE: Annotating with {} labels".format(len(labels)), labels) 131 stream = get\_stream( TypeError: object of type 'bool' has no len() Can anyone tell me what's the correct syntax. I am using prodigy v'1.8.3' ---

Hi! If I match the arguments to the `textcat.manual` method, it looks like you've forgotten the argument for `api` or for `loader`. Right now, `True` is being parsed as the argument for `label` (instead of your intended list) so this seems to be where the error comes from. Does it work if you call ```python prodigy.serve("textcat.manual", "esg_tagged_test", "en_core_web_lg", "./ESG_classifications_analystA.jsonl", None, None, ["ESG", "Not_ESG", "Confused"], True, None, port=9000) ``` instead? ---

Thanks this worked. ---

@SofieVL. Recently my organization has upgraded to version 1.9.9. Can you please tell me the syntax for this version. I tried the below mentioned snippet but it didn't work. ``` prodigy.serve("textcat.manual", "esg_tagged_test", "./ESG_classifications_analystA.jsonl", None, None, ["ESG", "Not_ESG", "Confused"], True, None, port=9000) ``` ---

Hm, that looks correct to me at first sight, for 1.9.9. Could you paste the error you're getting? ---

Thanks. Could you try again with ```python prodigy.serve("textcat.manual", "esg_tagged_test", "./ESG_classifications_analystA.jsonl", None, None, None, ["ESG", "Not_ESG", "Confused"], True, None, port=9000) ``` (i.e. one more `None` to fill the place for the deprecated variable `_` in the function call) ---

@SofieVL Thanks it worked but with a bug. When I run the above lines of code, the app starts on the given port but with an error. ``` Starting the web server at http://localhost:9002 ...

Hm, I'm not really sure what that last error means, especially if you say you checked the port. Are you able to reboot and/or try again in a fresh environment? Perhaps you've ended up in some inconsistent state after upgrading?
