In trying to execute the following....

```auto
tag_names = ['[System]Gateway/SystemName', '[System]Client/User/Username', '[System]Client/User/OSUsername']
tags = system.tag.readAll(tag_names)
print tags

```

Getting NPE

Would expect a list of qualified values returned.

Running 8.0.0-beta0 (b2018121302) in the Script Console.

I’m able to replicate this in the script console, although the function seems to be working correctly in the Client; I will open a ticket.

Please note that the readAll function is essentially deprecated, and has been replaced by readAllAsync.  
Also note that Client Tags are not accessible in Perspective Sessions, so expect `null` values with `Bad_NotFound` quality for any Client tags in Perspective.

Ok, thanks. Its failing in other parts of my scripts in the Designer too, so debugging is a bit difficult.

Understood. Like the new scope details in the docs. At this point, I'm just checking upgrade paths of existing 7.9 Vision code.

It’s specifically Client tags (try removing the Client tags and suddenly it works fine). Not sure if that helps you for now, but I noted it in the ticket.
