The function append(basemap, thumbnailUrl, tooltip) is sometimes called with just a basemap provided as argument, which causes the thumbnailUrl and tooltip to be undefined.
This causes a massive wave of errors when running the tool. Fortunately, fixing it was simple enough.
With this modification, the behavior did not change, but the errors all went away.
