> Can we use this function system.tag.importTags to create vision client tags ? collisionPolicy = "a" filePath = "d:/test.xml" basePath = "[client]" system.tag.importTags(filePath, basePath, collisionPolicy) return java.lang.NullPointerException (Ignition 8.0.10) Is there any way to create a cision client tag by scripting in Ignition 8 ? system.tag.configure only support gateway tags but not vision clients tag ?

but from the designer/client scope:

```auto
from com.inductiveautomation.ignition.common.sqltags.importexport.TagXMLImporter import TagXMLReader

```

return

```auto
Traceback (most recent call last):
  File "<input>", line 1, in <module>
ImportError: cannot import name TagXMLReader

```
