Cannot load widget

[StahlyEngineering]

I created an instance of the WAB server on my machine to debug a widget from a previous question I had.

On that instance I can add a previously developed widget "GetParcelRecords", and load an app with good results.

However if I change the manifest, by renaming the widget and the internal files accordingly, adding the widget throws the following error:

FeatureActionManager.js?wab_dv=2.5:174 Uncaught TypeError: Cannot read property 'en-us' of undefined
    at Object.<anonymous> (FeatureActionManager.js?wab_dv=2.5:174)

I have attempted to add the Demo widget and doing so results the same error.

I suspect that there is some fault with the server or its dependencies. Is there a way to check for that?

Is your browser and OS set to use the English language?

[StahlyEngineering]

Yes on both counts.

We are getting frequent server stoppages due to bad manifests, could that be related?

[RobertScheitlin__GISP]

Sounds like it would be related. This is going to be a hard on to diagnose.

Sounds like a bad install.
