getTargetBlockExact returning null incorrectly

[Klikini]

I am a developer of the Mine Assistant plugin for Bukkit, and I have received a bug report about it not working on Paper via Cardboard. The error returned is caused by the command sender (which must be a player) not having a block targeted.

• User's bug report
• Line of code in question (max target distance = 5)

Is there a difference in implementation such that we should check for Cardboard and make the call a different way, or is this a bug?

Should be fixed now.
