TaggerGetCurrentTag no output

[davidpede]

Trying to use TaggerGetCurrentTag snippet but it is not outputting anything. Have used like:

[[!TaggerGetCurrentTag? &groupTpl=`@INLINE [[+name]]` &tagTpl=`@INLINE [[+tag]]` &tagSeparator=`, `]] and [[!TaggerGetCurrentTag]] but nothing is returned. No errors in log.

Debugged the snippet and the $currentTags array and $output array are always empty.

Am I missing a parameter or something?
