We're up to 10 apps in our WAB 2.0 edition, and started getting this error "Error: duplicate key error index" and rattles off a bunch of node_modules errors... - any idea what we can do to try to repair. Aside from re-installing WAB 2.0 I'm out of ideas. If we were to re-install WAB, is there a way to backup and re-load our existing webapps? Thanks for any ideas.
