Apps not showing in WebApp Builder Developer

[MarkCooper5]

Hi

I was working on an app today and it it wouldn't save. I exited WAB Dev (inc node.js) and restarted it, but it came up with the following error:

Does anyone have any idea how to resolve this?

Thank you

Mark,

  Sounds like your apps database got corrupted. This is bad and there is no easy way to restore it. There is a manual way to restore it though.

1. Download WAB Dev again (same version) and extract it to a folder with a different name. I.e. I use C:/web-appbuilder-2.10 so this time call it C:/web-appbuilder-2.10_2 or something. DO NOT overwrite your old folder.
2. Next register the WAB Dev and create a new app and give it some generic name and save. Now copy the app(s) from the old WAB dev server folder into the new one. You will have to create a new app in the new WAB dev for each app you are attempting to recover. I.e. C:\web-appbuilder-2.10\server\apps\2 copy the contents of this folder into the C:\web-appbuilder-2.10_2\server\apps\2 folder.

Thanks Robert

Luckily we had a full backup in the end so could reinstate the files. No idea how this  got corrupted though.

I've had the same issue after killing a node.js task and restarting WAB's startup.bat, rebooting the server did the job and my apps were back
