I installed LocalLayer 2.0 and try the WAB 2.0 and WAB 2.1.
I get this "create widget error: widgets/Coordinate/Widget" error when I switch among different themes. If I remove the LocalLayer widget configuration from the config.json of the default layout of each theme, then this error does not occur.
Not sure if the problem is caused by the layers I added into the LocalLayer configuration.
Appreciate if anyone could help debugging.
