1652679 - Pretty-printing an anonymous file while paused in it causes debugger UI to turn white

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P2)

Description

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

This is cloned from https://github.com/firefox-devtools/debugger/issues/8270

STR:

1. Go to http://walmart.decipherinc.com/survey/selfserve/53a/wal18003
2. Go to debugger
3. Activate Event Listener Breakpoints: "click"
4. Tap on Continue at the bottom of the page (the debugger opens)
5. click { } at the bottom of the window

AR: The Debugger panel content is blank
ER: The Debugger (pretty printing) works as expected.

This doesn't look like being related to pretty printing itself since the formatted source appears for a moment and than it breaks.

There is an error in the Browser Console

Error: Resource source-server0.conn0.child2/source42/originalSource-21eb1fc094f510399f0fb9e6f2c15d92 does not exist selector.js:37:11

Logan, can you please look at this one.
What do you think should be the meta in this case?

Thanks!

:Honza, if you think that's a regression, then could you try to find a regression range in using for example mozregression?

We're accidentally creating mismatched sourcemapping information for the pretty-printed file so while pretty-printing succeeds, when we query the worker for position information, we get back a non-existent source ID, and when we try to use that source ID to highlight the DebugLine, it throws.
