Hey @DurchblickerFabian thanks for writing in! I'm not entirely sure what's going wrong here but I traced it back to where I think the error is happening and opened a quick fix PR (#11157) to prevent the error.

I'm gonna tag @edwardgou-sentry and @AbhiPrasad to take a more detailed look because it's a bit unclear to me how we could run into the situation that the entry is missing.

Expect the fix to be released with the next version within this week. Thanks!

I'm also experiencing this issue.

In my instance, the interactionIdtoRouteNameMapping argument to the _trackINP function was an empty object.

Hi @jketcham this should be fixed via #11183 once it's released. Should happen in the next days.

Released with https://github.com/getsentry/sentry-javascript/releases/tag/7.108.0 - thanks for your patience!
