Got a strange error in one of my apps:

[2023-09-08 00:18:09,216] ERROR in app: Exception on request POST /bla

KeyError: 'QUART_SCHEMA_CONVERT_CASING'

Solved it by ensuring the key is present:

app = Quart(__name__)
app.config['QUART_SCHEMA_CONVERT_CASING'] = False

Should this be .get() ?

Are you initialising the extension?

app = Quart(__name__)
QuartSchema(app)
