I’m not sure what’s special about Symfony’s Request but I wasn’t able to reproduce the problem with a custom code.

Surprisingly, the error shows even here: https://getrector.org/demo/15c3fd41-9764-4f6d-8f3e-e9ccc36b252d

Different line numbers (180 vs 137) because of unprefixed vs prefixed version
