Lost connection with server: message too big (1009) #745

Closed matkuki closed 10 months ago

matkuki commented 10 months ago

Hi,

I have a flexx application that is working great, but after a few years of operation, a few databases have gotten quite large (over 40MB of JSON data to send through a WebSocket) and sometimes when updating the data from the backend to the web-browser, I get an application crash and the following message:

Lost connection with server: message too big (1009)

I have read in a few places that this limit on WebSockets can be changed, but I don't know where to do it in flexx. Could someone point me to where this can be changed?

Thanks Matic

I read here that you can add the websocket_max_message_size param to the Application constructor (requires Tornado 4.5):
