Chat session with Claude 3.7 Sonnet goes blank after a while

I’m in the middle of refactoring some code and the chat session with Claude 3.7 Sonnet keeps going blank after a few messages. The entire page just becomes blank and only shows the title of the chat session at the top.

Going to History and trying to access it from there also gives a blank page. I have to start a new chat session every time.

This already happened twice.

Edit: I’m using Cody Chat on sourcegraph.com not the VSCode Extension.

This is what I see in the console:

TypeError: e.message is undefined
    Immutable 10

Uncaught TypeError: e.message is undefined

Hey @Halnex

This might be related to exceeding the token window and the chat breaks unfortunately.

We also experiencing a limit on usage of Sonnet 3.7 today because Anthropic has a hard time scaling the servers with that amount of general usage.

I see. Well Anthropic has always been poor with their infrastructure, let’s hope they fix this asap.
