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 providers (such as Claude and Codex) are part of paid plans. 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.
