You may need an additional `except` clause:

```auto
except java.lang.Exception, e:

```

It’s almost certainly failing because a gateway tag change script has no concept of a ‘default user source’, so attempting to use the empty string parameter is failing.

What value should I pass as the `userSource`?

Perhaps I should ask, where do I look to know what the `userSource` should be?

Looking at the documentation for `getUser()` . . .

[https://docs.inductiveautomation.com/display/DOC81/system.user.getUser](https://docs.inductiveautomation.com/display/DOC81/system.user.getUser)

in regards to `userSource`, it only says `String userSource - The name of the user source to search for the user in . . .`

OK I found it, in the Gateway. In my case it was ‘default’, passed as the `userSource`, this worked. Thanks for the info. .

I'm going to try your suggestion too. Thanks for mentioning that. I've been stumped several times in the past where scripts just terminate without triggering the error handlers. It's as if nothing happened and nothing is brought to anyone's attention until users notice odd behavior.
