Fresh installation of the nextjs sentry sdk gives warning messages in console?

[mild spindle]

Seeing the following messages come up when running next dev after a fresh installation of v8 on next 14.2.3:

[@sentry/nextjs] It appears you've configured a `sentry.server.config.ts` file. Please ensure to put this file's content into the `register()` function of a Next.js instrumentation hook instead. To ensure correct functionality of the SDK, `Sentry.init` must be called inside `instrumentation.ts`. Learn more about setting up an instrumentation hook in Next.js: https://nextjs.org/docs/app/building-your-application/optimizing/instrumentation. You can safely delete the `sentry.server.config.ts` file afterward.
[@sentry/nextjs] It appears you've configured a `sentry.edge.config.ts` file. Please ensure to put this file's content into the `register()` function of a Next.js instrumentation hook instead. To ensure correct functionality of the SDK, `Sentry.init` must be called inside `instrumentation.ts`. Learn more about setting up an instrumentation hook in Next.js: https://nextjs.org/docs/app/building-your-application/optimizing/instrumentation. You can safely delete the `sentry.edge.config.ts` file afterward.

Any thoughts? Can't find anything on github issues about it

Are the logs valid? Did you run the installation wizard or did you bump the package on an existing project?

the initialisation for next js changed in v8. You need to add a instrumentation.js file to your project.
More details are available in the manual setup doc: https://docs.sentry.io/platforms/javascript/guides/nextjs/manual-setup/#create-initialization-config-files
