I have checked the following:

  • I have searched existing issues and found nothing related to my issue.

This bug is:

  • Making Bruno unusable for me.
  • Slowing me down but I'm able to continue working.
  • Annoying.
  • This feature was working in a previous version but is broken in the current release.

Bruno version

4.1.10

Operating System

Windows

Specific OS Version / Distro

Describe the bug

The problems:

  1. After switching gRPC collection, reflection not updated automatically
  2. After manual refresh current selected method is none and not updated

Workaround: 3. Close Bruno 4. Open Bruno 5. Now current method is set correctly

Possible solve:

  1. Having ability to start multiple instances of Bruno
  2. Fix problem by design (cache reflection data until refresh)

Steps to reproduce

  1. Open gRPC collection "collectionA" having reflection
  2. Switch to gRPC "collectionB" having reflection

Collection to reproduce
