Hello,
I am experiencing a persistent synchronization issue with the Google AI Studio Build Preview.
Project: Ma To-Do Fitness
App ID: 0c4eb693-479a-4986-a9c9-7bc2d8c4c2bc
The integrated Build Preview is not displaying the current version of my application.
I have verified the following:
1. The development server runs correctly on localhost:3000.
2. /src/main.tsx is served correctly.
3. The application import chain has been verified:
main.tsx → App.tsx → AccueilTab.tsx → EnergyHeroCockpit.tsx
4. EnergyHeroCockpit.tsx was intentionally modified with an unmistakable visual diagnostic:
- bright red background
- 10px lime border
This was specifically done to determine whether the Preview was executing the current source code.
5. Direct HTTP requests to the development server return the updated EnergyHeroCockpit.tsx with HTTP 200.
6. The corresponding CSS classes are also served correctly with HTTP 200.
7. Despite this, the integrated AI Studio Preview continues to display the previous version of the application and never displays the red/lime diagnostic.
8. Clicking “Reload the app” does not update the Preview.
9. Restarting the official development server also does not update the Preview.
10. Network monitoring showed that reloading the Preview does not generate the expected request to the development server.
11. The issue was also tested from another browser context, without resolving the problem.
This strongly indicates that the integrated AI Studio Preview is rendering a stale snapshot/version of the application rather than the current development server output.
The problem therefore appears to be in the AI Studio Preview / proxy / synchronization infrastructure rather than in the application code itself.
Please investigate the connection between the Build Preview iframe and the current ais-dev Cloud Run development endpoint.
I have deliberately stopped modifying the application to avoid introducing unrelated changes while this infrastructure issue is investigated.
I can provide screenshots and the complete
technical diagnostic if required.
Thank you.
