I’m hoping to get some help with a critical issue I’ve been facing.
I’ve been working on a significant project with v0.dev for a long time and have invested hundreds of dollars in credits so far. Very recently, the yellow warning message “Long chat detected” has suddenly appeared across all of my projects at once, with a “Fork” button next to it.
At first, I thought my main chat was simply too long, which seemed reasonable. However, I have another, older project where the chat history is at least three times longer, and it doesn’t have this warning at all.
To investigate further, I checked a much smaller project with only about 70 prompts/edits in the chat history, and it’s showing the same “Long chat detected” warning. It seems this is now affecting all of my projects, regardless of their actual chat length.
The biggest problem is that this has made the Preview feature completely unusable. I’m currently completely blocked and can’t continue working on my components.
Has anyone else encountered this? Is this a known bug, or is there a potential workaround I could try?
I’m really hoping this is just a temporary technical glitch on the platform’s side that can be resolved soon.
Any help or suggestions would be greatly appreciated.
The “long chat detected” alert is a recent feature and aimed to improve generation quality because AI model performance gets worse when the context window is filled with old requests and versions of the code. This didn’t exist on your previous long chats but will probably appear if you start interacting with it again
You can ignore it and continue development as usual, so it shouldn’t block anything for you
However you mention “it has made the preview feature completely unusable” which should be unrelated to the Long chat detected system. If you’re seeing a disabled preview, this is almost always because your project contains modules that are known to not work inside v0’s browser preview environment.
I checked one of your recent chats and the preview is disabled because the project uses “google-auth-library” which requires node child_process to run and therefore doesn’t work in the v0 preview. If you hover over the preview tab (which should look like an eye crossed out it will tell you why the preview is disabled. google-auth-library was added to the list of packages known to break v0 previews 11 months ago, so if you are trying to load a chat older than that, that could explain why you’re now seeing issues
