I’ve searched and found this error reported multiple times, often for different reasons, and I’ve noticed that the suggested fixes vary depending on the case.
Context
I’m on a pro subscription
This project has been built entirely inside v0 over a sustained period
It includes a large number of .tsx files, App Router pages, and assistant-generated scaffolding
The assistant has been used continuously to build, edit, and refactor the full app structure
What’s Going Wrong
Any new prompt is blocked, even when it contains only a short instruction
Starting a new chat within the same project results in the assistant saying it cannot access known files (e.g., app/page.tsx)
I haven’t tried forking individual components because I’m working on full app-level changes (e.g. fixing files, renaming, restructuring)
I’m also currently blocked from completing a working Git deploy due to build errors that can’t be addressed while this messaging issue persists
Assumptions
The assistant context for the current chat may have grown too large from extended use
The error may stem from a memory limit rather than actual prompt length
New chats appear disconnected from the file system, even when launched from the same project
What I’m Hoping to Resolve
Is there a way to reset or clear chat context without losing the project’s file structure?
Can assistant access be restored to a project when new chats fail to recognise existing files?
Are there known limits or best practices for managing long-running v0 projects?
Did you know about these other v0 resources? A human should be here soon to help, but the answer may already be available even faster in one of these other posts.
This guide is a great place to start.
And these recordings can give you a look at v0 features and strategies in action: Topics tagged v0
This sounds similar to the situation recently discussed here:
Reducing the size and complexity can get rid of the error. You can create new chats scoped to components or features. Or you could download the code, simplify your local copy, and upload the less complex code to a new chat
I tried downloading the code and uploading it to a new chat (didn’t accept a large number of UI components I had already built in it (so will have to re do all of those AGAIN)
From the new chat I’ve tried:
Minimal scoped prompts - reduced the prompt to just include basic modal setup and core logic.
Incremental build strategy - attempted to build the modal in small steps: shell first, then follow-up prompts to add specific features.
Ultra-short test prompt - tested a basic Dialog component with no logic, to rule out complexity.
I just reached out in a private message. Please let share a link to the chat there so I can dig into the logs for more details about what’s going wrong
Coming back to share the solution in case it helps anyone else. In this case, @zogcorp decided the project had gotten so large that it made sense to download the code and finish up with Cursor
