Troubleshooting
Quick answers to the things people actually hit.
My preview isn’t showing
Section titled “My preview isn’t showing”The first build takes 1–2 minutes. While it runs, the Preview tab shows “Building your app — the first build usually takes 1–2 min…” — switch to the Logs tab to watch progress.
If the build has finished but the preview looks blank or shows an error, the container may still be booting — click Reload in the preview header. If you see “No preview yet. Send a message to build this project,” the project hasn’t built successfully yet; send a message to kick off a build.
My build failed / the project shows ERROR
Section titled “My build failed / the project shows ERROR”A project shows ERROR when its last build didn’t finish — the agent hit its
time limit, or the run ended with an error. The error appears in the chat. Just
send another message (for example, “try again” or a more specific
instruction) to queue a fresh build on top of your existing repo.
I hit my daily prompt limit
Section titled “I hit my daily prompt limit”Each plan has a daily allowance — Free 5 / Pro 20 / Max 100 prompts, where a prompt is one build (creating an app or sending a chat message). You’ll see:
You’ve used all 5 prompts for today on the Free plan. Upgrade for more, or come back tomorrow.
The count resets at 00:00 UTC. To keep building now, upgrade — see Plans & limits.
My magic link didn’t work
Section titled “My magic link didn’t work”Sign-in links expire after 15 minutes and are single-use. If yours has expired or was already clicked, head back to the login page and request a new one.
I got a validation error
Section titled “I got a validation error”Lyvica needs a little to work with:
- Project name — at least 2 characters (“Give your project a name (2+ chars).”)
- Brief — a sentence or two (“Describe what to build in a sentence or two.”)
- Chat message — at least 2 characters (“Message must be at least 2 characters.”)
Can I build something other than Next.js?
Section titled “Can I build something other than Next.js?”Not yet — Lyvica builds Next.js apps today. Other frameworks aren’t selectable.
Can I rename a project?
Section titled “Can I rename a project?”Yes. Renaming changes the display name only — the project’s URL, GitHub repo, and preview address stay the same.
Where’s my code / preview?
Section titled “Where’s my code / preview?”Every project has a private GitHub repo in the Lyvica organization (open it
with the Repo button) and a public preview at
https://<your-project>.preview.lyvica.com (the Open button).
API errors
Section titled “API errors”When using the API, errors come back as
{ "error": { "code", "message" } } with these statuses:
| Code | What it means | Fix |
|---|---|---|
401 | Missing/invalid API key | Check the Authorization: Bearer lyv_live_… header; create a key in Settings |
404 | No project with that id/slug | Verify the id or slug |
422 | Validation failed | Lengthen the brief / message |
429 | Daily limit reached | Wait for the 00:00 UTC reset, or upgrade |
400 | Body wasn’t valid JSON | Send valid JSON with Content-Type: application/json |
