"Chat is too long" despite starting a new chat

[nickz22]

Describe the Bug

I’m receiving a “Chat is too long” error even when I’ve started a fresh thread

Steps to Reproduce

I’m unfortunately not exactly sure…I suppose you could max out a thread and change to a new one.

Expected Behavior

I expect that chat length limitation to abide by the actual size of my current chat, which in the screenshot is 0 messages.

Additional Information

I tried reloading the window and the problem persists. I’ve tried changing from Agent to Ask and got the same error.

Does this stop you from using Cursor

Cursor is sometimes usable

Maybe the search for current chat length is using the exact chat content to match against saved chats in the database, and then reading that saved chat as the length of the current convo.

I added “Please” to my current chat and it let me continue.

It actually appears to be the git changes that were too large - I noticed the issue recur, and cease to occur after I removed the git changes.

I often do /reset context when starting a new chat because i noticed too that it holds the context from the last chat and i did not get this type of error in a long time.

Yeah, will mark this as the solution since I noticed the same - thanks!
