I'm using Next js 15 and React 19 for a web app and I'm having issue with installing Sentry into my project. While trying to install sentry I get the following error:
◇ Installation failed.

I checked if sentry is not compatible with react 19, and it is compatible
The conflicting peer dependencies likely come from somewhere else than Sentry in your project. You should be able to manually install the @sentry/nextjs package and then rerun the wizard and then it will ask you whether you want to install/update it.
Or you can simply re-run the wizard with the --force-install flag, which should bypass the peer dependency check.
