APPENDIX
Your survey responses stay in your own Qualtrics account, on your institution's servers. We store conversations only if you set ResponseID in the study object, and delete them 180 days later. Leave it out and we save nothing.
Open your browser's developer tools — F12 on Windows, Cmd + Option + I on Mac — and click the Console tab. Errors there usually name the problem. In Safari, first select "Show features for web developers" in Settings > Advanced.
Disable Bot detection and/or Security scan monitor in Qualtrics survey options settings. These features can interfere with the chatbot.
404: NOT_FOUND. Code: DEPLOYMENT_NOT_FOUNDCheck your app expiration date.
402 (or the app hangs waiting for a reply)This is a credit limit, not a model permission. OpenRouter reserves the full maxTokens budget up front, so a model with a large default context can exceed your remaining credits even though cheaper models go through. The error reads "This request requires more credits, or fewer max_tokens". Add credits, raise the key's limit, or set maxTokens in the model options object. When stream is false, the failure often shows as the app waiting indefinitely rather than an error message — check the browser console.
