Steps to Reproduce
After upgrading @sentry/nuxt from 9.5 to 9.8 on March 26, 2025 at 1:54 PM, the customer noticed a large spike in spans reported to Sentry, despite having no changes to their tracesSampleRate (which is set to 0.001). Reviewing the changelog didn’t reveal any obvious reasons for this increase.
They deployed the update on 3/26/2025 at 1:54 PM. Since then, they upgraded to the latest version 4/9/2025, 2:38 PM UTC and they haven’t seen any changes in the stats in Sentry (they did disable Sentry from our production application though, so that’s the reason for the drop of events in the end of the graph.)
Expected Result
The incoming span count should have stayed roughly the same after the upgrade
Actual Result
The incoming span count increased
