[EP-tech] Re: Issues following database change (possibly...)

Hi Andrew,
If the double --verbose flag doesn't give you the clues you need, you might need to add some
print STDERR "\nI got here [x]\n";
lines to the generate script (and possibly some of the modules it calls)

usual caveats about backup copies of stuff before breaking them though!

Okay, update here...

Nothing to do with my changes whatsoever! This is apparently an issue that we’ve simply not noticed yet and would appear to be related to the AuthorID script trying to process some data that it’s not expecting. This could be something coming through from LDAP. Does the generate_views script write any kind of data dump, or is there a way to get it to do this, so that I can check what it’s trying to process at the point that it falls over?
