TypeScript code:
const url = '<REDACTED>/server/services/CRSMS/results_views/MapServer/WFSServer';
wfsUtils.getCapabilities(url).then((capabilities: __esri.WFSCapabilities) => {
console.log(capabilities);
wfsUtils.getWFSLayerInfo(capabilities).then((layerInfo: __esri.WFSLayerInfo) => {
console.log(layerInfo);
}).catch(err => console.error(err));
}).catch(err => console.error(err));
Full error object:

I tracked down the line in wfsUtils.js that attempts to call e[0].toFixed, and the error seems to stem from trying to run toFixed on an array.
This is the object assigned to const "l" (that's a lower case "L") in the _ function in wfsUtils.js
{
"type": "LineString",

}
This gets interpreted as a 'lineString', type, and a switch/case assigns l.coordinates[0] to e
It seems like this is the issue. With these coordinates, the assignment should go a level deeper: l.coordinates[0][0] (which is what the switch/case uses for types MultiLineString and Polygon.
The question here is this -- is my service returning the wrong type and/or coordinates data, or is wfsUtils handling this wrong?
Any help or clues would be appreciated. Thanks!
