Error after update to Nextjs 15

[joncoronel]

Updated to Nextjs 15 and it seems openpanel breaks after the update. It seems to only occur in the turbo dev server. Does not occur in production. If I remove the --turbo from the dev server, it seems to work. Although, I did not get this error before upgrading even when using turbo before. Simply importing import { OpenPanelComponent } from "@openpanel/nextjs"; causes the following error to occur:

TypeError: 'ownKeys' on proxy: trap returned extra keys but proxy target is non-extensible

Thanks for the report. I'll have a look

Just tried on a fresh installation of nextjs 15 without any issues. Can you create a reproducible repo where I can check?

[joncoronel]

Okay, so tested a bit more and the error occurs when both --turbo is enabled and the root layout is set to export const runtime = "edge";.

Also replicated here. Fresh install of next 15 and react 19.

Great, I could reproduce the error now. Will give to solve this

Late on this but I know the problem. Just need to dig a bit more into this since it breaks on nextjs pages folder if I do this change. Hang in there
