A/B testing: error page

Hello,

I’m experiencing an issue with A/B testing on my website built with Nuxt.js v3.19.3, running in SSR mode, and using Storyblok as the CMS.

I configured A/B testing on two environments: development and production.

In development, everything works correctly regardless of the traffic split between the branches.

However, in production, several problems occur:

  • Some pages enter an infinite reload loop

  • SSR-fetched data sometimes does not load at all

  • Multiple JavaScript errors appear related to chunks

Please note that prerendering is enabled on the production environment.

Do you have any insight into what could explain this different behavior between environments, or any specific Netlify configuration to check when using A/B testing with a Nuxt SSR + prerender setup?

Thank you in advance for your help.
