How to test 🧪

Prerequisites

• Use MSW crud and custom profile preset. In the profile dialog, make your user restricted (see ticket for imgs/videos)

Reproduction steps

• Something went wrong dialog appears

Verification steps

• No error appears - you can use MSW as expected
• Test out the new custom grants preset too - confirm changes made to your grants get saved and reflected in the MSW (example: change global add_firewalls preset to false, confirm Create Firewalls button gets disabled)
