agent scheduler is not compatible with gradio 3.45 and higher

[vladmandic]

for example, using gradio==3.45.2.:

KeyError: 'trigger'

this is likely caused by change in gradio in this pr: 5639

[artventuredev]

I've set gradio to version 3.45.2 in the latest master and made some modifications to ensure the code functions. However, I was unable to launch the webui, and encountered errors in the browser console. Despite disabling the extension, the errors persisted, indicating they're likely not related to the extension. Is there anything else I need to do to make the code compatible with the new gradio version? Anw, you can try the modified code in branch fix/new_gradio.

i was just debugging that. it seems like a bug in gradio introduced via https://github.com/gradio-app/gradio/pull/5384 and breaks gradio dropdowns with multiselect enabled.

basically, gradio svelte function that handles multiselect has its params offset by one, so label becomes type, value becomes choices and choices become null. i'll follow-up with gradio team.
