Error in if: argument is of length zero

[xorb0ss]

The TDMSviewer itself opens in my browser, and the interface works, but it doesn't actually load any TDMS files correctly, due to the error Error in if: argument is of length zero

Here are the steps I take:

library(tdmsviewer)
tdmsviewer(basedir='~/data/tdms')

When I select a TDMS file to open:
