Auval Error -1,0xFFFFFFFF

Hello people,

Is anyone aware of this error?

FATAL ERROR: OpenAComponent: result: -1,0xFFFFFFFF

validation result: couldn’t be opened

I was testing a plug-in using the command line AuvalTool and it failed, returning this error. Unfortunately, I couldn’t find anything around.

Any idea were could this come from?

If you take a copy of auvaltool and place in your home directory you can then use that as the Executable for a Debug build in XCode, and add the appropriate arguments to Arguments Passed On Launch on the Arguments panel when you Edit Scheme…

This might at least give you a clue if some exception is being thrown by your plugin during validation, or you can set some breakpoints and step through your code to help nail it down.
