1558423 - TypeError: categories is undefined

Status: RESOLVED INVALID

(DevTools :: Debugger, defect, P1)

Description

[Jan Honza Odvarko [:Honza] (always need-info? me)]

I am seeing the following error in the Browser Console (it makes the entire Debugger panel blank)

Looking at the state:

state.eventListenerBreakpoints.categories is undefined

Could fetching of AVAILABLE_BREAKPOINTS from the backend fail?

Sorry, I don't have STRs, but I still think it's good to file the bug here. It worked before and suddenly stopped.
Of course, creating a new profile helps.

How/where can I simple check that fetching AVAILABLE_BREAKPOINTS works?

Ah, I was accidentally using different backend (not Logan's build)
