Matrix Out Node error

Created by: DolphinDream

It seems that either Matrix Out node has some issues with the input.. (from various matrix generating nodes). Note: this is on master branch.. with the MK2 Matrix In node. Same error occurs if feeding in matrix from Matrix Euler node.

With the following error:

Can someone confirm this is an issue with the Matrix Out node? or perhaps with the socket converters?
