Troubleshooting: AI & Provider Errors
These errors come from the AI provider while running a chat, rather than from the plugin itself. The plugin loaded and connected fine — the model request failed.
“Context length exceeded” / prompt too long
The conversation plus its context is larger than the model’s maximum context window.
- Start a new chat to drop accumulated history.
- Attach fewer or smaller files and
@-mentions. - Switch to a model with a larger context window from the model picker.
“Available on Ziva Pro and Ultra”
Some hosted models (such as Claude Sonnet, Claude Opus, and Ziva Genius) are part of Pro and Ultra. Connecting your own Claude Code or ChatGPT Codex subscription works on every plan. If you see a message like “…is available on Ziva Pro and Ultra,” the selected provider isn’t included in your current plan.
- If you’re signed out, sign in first — your plan can’t be checked otherwise.
- Upgrade your plan, or pick a model that’s available on your current plan.
Billing or checkout problems
If checkout won’t open or plans won’t load (“Failed to open checkout” / “Failed to load plans”):
- Make sure you’re signed in.
- Allow pop-ups / external links so the checkout page can open in your browser.
- Check that you can reach the Ziva website normally; a proxy or firewall can block the checkout redirect.
Local models (Ollama / LM Studio) don’t appear
This is covered in detail on the Local Providers page. In short: the local provider app must be running, have a model loaded, and be reachable at its configured host/port; refresh the model list after starting it.
