No - Cursor works, but with this issue

Hello, you seem to successfully fix the vertical bug, but now the model is not able to make tool calls.

[deanrie]

Thanks for the additional info. We’ll investigate this.

Asked Kimi K2 a question 1 hr ago and it gave me half the response and stopped due to a network error. I’ve been trying to continue the convo for the past hour but everytime I get the same response “We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.

Thanks for the info. We’ll try to figure out the cause.

Issue is still occurring even on new chats using Kimi K2. it would give a 1 line answer do a tool call then on the next tool call it would stop giving the same error. I disabled privacy mode and clicked on copy request info and I’m pasting it below

Request ID: 7729bdc1-f51f-47d9-b8a7-498b292969a4

This is a bug since I have a workaround. If I close the chat window and reopen it from the history, then it displays correctly.
