Destination quadrilateral of width 0 throws error

[rynobax]

var PerspT = require('perspective-transform');
const src = [ 0, 0, 0, 1024, 1024, 0, 1024, 1024 ];
const dest = [ 512, 171, 512, 853, 512, 0, 512, 1024 ];
var perspT = PerspT(src, dest);

When I try to map to a quadrilateral where all the x coordinates are the same, I get the following error:

TypeError: Cannot read property '3' of undefined

I poked around in the code a bit to try to come up with a nice solution, but the best I could get was throwing in a check like:

if(dstPts[0] === dstPts[2] && dstPts[0] === dstPts[4] && dstPts[0] === dstPts[6]){
    this.coeffs = [0, 0, dstPts[0], 0, 1, 0, 0, 0]
    this.coeffsInv = [0, 0, 1/dstPts[0], 0, 0, 0, 0, 0]
} else if(dstPts[1] === dstPts[3] && dstPts[1] === dstPts[5] && dstPts[1] === dstPts[7]){
    this.coeffs = [0, 1, 0, 0, 0, dstPts[0], 0, 0]
    this.coeffsInv = [0, 1, 0, 0, 0, 1/dstPts[0], 0, 0]
}else {
    this.coeffs = getNormalizationCoefficients(this.srcPts, this.dstPts, false);
    this.coeffsInv = getNormalizationCoefficients(this.srcPts, this.dstPts, true);
}

This just maps everything to a line that is the height of the source quadrilateral and on the x coordinate that all the x points of the destination quadrilateral are on, which is fine for my use case, but I feel like there could be a better solution.
