FB3 Debug: Launch Failed: Invalid argument

[Stephen Downs]

I've having an extremely agonizing time dealing with mysterious alert  
messages when trying to debug my Flex Builder 3 project. Debugging  
begins, the status bar reads "Launching project: (91%)", the  
application loads in the browser and displays, but back in Flex it  
hangs with an error message:


Launch Failed

Invalid argument


This error message could be more informative. As is, no details, no  
line number given.

Fixes I've tried, in combination and alone, to no avail:
        ) Clean Project.
        ) Strip mxml down to single bare Application tag.
        ) Delete build folder.


Install details:
Mac OS X 10.6.1
Safari 4.0.3 (6531.9)
Flex Builder 3.0.2
Flash Player 10.0.32.18 content debugger

Any insight would be terrific.

Thanks,
Steve

Have you tried debugging your app with FireFox?
I'm also on a mac but have never tried debugging using Safari

Cheers

In Eclipse, try to open the 'Error log' view, and you will get more precise
informations about the errors you encounter.

Wow total voodoo: the error just disappeared after I quit Flex Builder  
and launched yet again (I forgot to mention I tried doing this several  
times as well). The only thing different I can think of is that Safari  
launched first in this debug session.

I will try Firefox if this rears it's head again.

Error Log view was no help. It did not include any of these errors.

Thanks for the help. Problem mysteriously solved for now.
