Duplicate key index error?

MichaelAugust — Thu, 14 Apr 2016 18:57:27 GMT

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.

Michael,

When I have had a WAB install get corrupted and am no longer able to make new apps I just install a new WAB under a different folder name and use that one for creating new apps and keep the old one to get access to the other apps. You can (I have done it in the past) export from the other WAB and then import to the new WAB.

Great, thanks Robert, didn't think of that and it makes sense. If we've also developed a style (a new swatch to choose) under a theme (i.e. Foldable), for example we created a new color style under the Foldable Theme, is it ok to just copy/replace inside the themes folder to the new WAB install? trying to understand best practices when something blows up like this, so we don't have to redo that style creation work...thanks for your help!

Michael,

I have done the same (creating a custom style). Yes that will work.

I have run into this situation too, where I cold no longer duplicate apps for whatever reason. My solution was to export the app I wanted to duplicate, then import it.
