Python Error with QGis2Web on QGIS 3.6.3 Noosa

Question

I'm receiving a Python Error when trying to create a web map using QGIS2Web and for the life of me cannot figure out what to do.

Running QGIS 3.6.3 Noosa Windows 10 Professional

KeyError: 100

The error message says that the key 100 is not found in this line uri = TYPE_MAP[layer.wkbType()]. So layer.wkbType() returns 100 which is the code for NoGeometry. So I guess you have a layer with no geometry set. If you can somehow disable or remove that layer it might work. Alternative try to update QGIS2Web. Looking at the source code you can see that an if statement handling layers with NoGeometry have been added 25 days ago: GitHub Blame (line 146)
