error in https://oi.geocloud.com/api/v1.1/js/viewer.js

I registered the Web AppBuilder widget with my ArcGIS Portal 10.7.1 (customer-driven). Published an OIC successfully and can configure it for use in the widget. However, when identifying a location, the widget fails to return an image. Some digging shows what appears to be an error in 'createThumbnailUrl' in https://oi.geocloud.com/api/v1.1/js/viewer.js (line 1243 in browser formatted version).

```
else if ("A|" === t.Image.substr(0, 2)) {
var r = t.Image.split("|")
```

t at this point does not have an attribute ```Image```. It does however have an attribute ```image``` that has a valid URL to the returned image.

after setting:
```
t.Image = t.image
```
in the browser console for the images returned from the search, the app does display the images properly.
