Hey, can you check (in your lockfile) that all your sentry dependencies are on the same version? Thanks!

I'm also seeing this — I'm working in a monorepo using pnpm, I only have @sentry/sveltekit@^7.56.0 installed, and my lockfile says that is indeed the version that's installed everywhere. However it has some deps that are resolving to 7.48.0, namely @sentry/bundler-plugin-core@0.6.0 is pulling in @sentry/tracing@7.48.0, which in turn pulls in core, types, utils, all at 7.48.0. I can share my whole lockfile if that helps.

This is a prod-breaking issue for me that I only got when upgrading all my deps so some insight or further debugging steps would be wonderful.

Hi @alexbjorlig and @madeleineostoja, thanks for reporting this. We missed a crucial edge case here - namely the client being undefined. I opened #8381 to fix this.
