Cannot save a pixmap to png using Flite.

When using these options for writing pixmaps, I get stdErr:"No format specified" in the Convert.js line 260 where the convert process close handler is

var pngSettings = { format: 'PNG32' , ppi: self.document.resolution , useFlite: true , getICCProfileData:true };

My previous png setting still work fine and I get images written to disk:
var pngSettings = { format: 'PNG32' , ppi: self.document.resolution , padding: padding };

My getPixmap setting are:
var getPixmapSettings = { clipToDocumentBounds: true, useICCProfile: this.document.profile, getICCProfileData: true }

Using caps "PNG32" is no longer effective if using Flite. Changing my settings to format:"png"
caused pixmaps to start saving, along with the proper icc profile.
