Description
I'm running a local copy of the demo and there's an issue with the Select form. Pressing "Submit" throws a server-side error, and the post
router method is never run.
I think the problem comes from the multiple select fields. Commenting these out, or converting them to single fields, fixes the problem, and the Submit button triggers to goto event leading back to the root URI. I read in other issues on here that arrays types in forms are not yet supported. For clarity, perhaps this should be removed from the demo until they are?
Also, I tried adding a handler like this in demo/__init__.py
:
from fastapi.exceptions import RequestValidationError
from fastapi.responses import JSONResponse
from fastapi import status
@app.exception_handler(RequestValidationError)
async def validation_exception_handler(request, exc):
print(f"Caught 422 exception on request:\n\{request}\n\n")
return JSONResponse(
status_code=status.HTTP_422_UNPROCESSABLE_ENTITY,
content={"detail": exc.errors(), "body": exc.body},
)
The 422 event is printed to the console, but the handler never gets fired. Why is this?

@charlie-corus,
Thanks for reporting this! Definitely looks like a bug in the demo. I'll have a bit more time later in the month to hone in on FastUI, so I can take a closer look at a fix then!
