CodeAIM Browser based interface disappears

Dougy_Lee · February 1, 2026, 8:48am

Hello!

I’m really sorry my first post on the forum is a bug report.
Every time I start the web page, the page loads up initially, but every time i open any drop down menu, it disappears. Video attached.

I also looked in the console for the error. I’ve added the stacktrace errors below.

Here are the relevant system details:

Browser: Vivaldi
OS: Linux (Ubuntu 25.10, Wayland)

I’ve tried it on:

Happens all the same.

Executing inline script violates the following Content Security Policy directive 'script-src 'none''. Either the 'unsafe-inline' keyword, a hash ('sha256-6GMkQIeU4LV/MOId5y6sFXjngAUi3R57X6EOYbLCMQ8='), or a nonce ('nonce-...') is required to enable inline execution. The policy is report-only, so the violation has been logged but no further action has been taken.

Hi @Dougy_Lee , and welcome to PD+! We are happy to have you here.

Unfortunately, Vivaldi is not a supported browser for VEXcode. The information at this link can help you get started with another one!

Let us know if we can provide additional help.

Dougy_Lee · February 2, 2026, 11:44pm

Hi @Aimee_DeFoe no problems. I can work around it by using it on Chrome on another Windows machine. I also installed Chrome on my computer. Seems like VEX Code browser is not supported on a Linux based system either.

Aimee_DeFoe · February 4, 2026, 2:36pm

Great! I’m glad you will be able to access VEXcode despite the initial bump in the road! And you are correct, Linux is not supported at this time. We’d love to see what you are working on with your students, so please don’t hesitate to share with us here in the Community!
