NoMethodError: undefined method `add_session' for nil:NilClass

Hi
Dependabot has created a PR for 4 repos and all of the repos rspec request spec are failing with the following error message.

NoMethodError:
       undefined method `add_session' for nil:NilClass

It updates sentry-rails & sentry-ruby from 5.15.2 to 5.16.1. I had a look through the release notes and cannot spot what might have changed between the versions to see this error crop up. All the other specs are passing.

Apps are Rails 7.1.2, Ruby 3.2.2 and using rspec/

Ah it seems to be related to this one lot of specs affecting all the request specs

https://github.com/alphagov/forms-product-page/blob/main/spec/integration/sentry_spec.rb

If I comment out this file then all the request specs pass. I think it has to do with the setting up/tear down in the before/after blocks thats having an impact.

I tried isolating the issue in a completely new rails app and everything passed but it didn't have this spec file in it.

Happy for any pointers otherwise, I'll continue to investigate on my own.

Many thanks
