Errors while setting up for Chainlit for local development.

SalamanderXing commented 8 months ago

I ran the instructions here to set up the repo for local development. But when I reach the step: chainlit run chainlit/hello.py this opens up a page on localhost:8000 as usual and when i type something I get:

Opening in existing browser session.
2023-12-31 11:28:43 - 'output'
Traceback (most recent call last):

    return await user_function(**params_values)

    content=f"Your name is: {res['output']}.\nChainlit installation is working!\nYou can now start building your own chainlit apps!",
                             ~~~^^^^^^^^^^
KeyError: 'output'

But this I easy fixed by changing 'output' key to 'content'.

Still, when I open up localhost:5174 (as suggested in the guid) and try to type something there I get another error:

KeyError: 'content'

This I get regardless of whether I use 'content' or 'output' in hello.py. But it's clear from the stack trace that the error does not come from there.

This is weird, content=_dict["content"] is used in Chainlit <1.0.0. The main branch of the repo is already at 1.0.0 so it should use output (source here). Did you pull the latest main?

My bad! I did but forgot to do a poetry install before doing poetry shell.
