Importing webpack/rollup processed code results with `Cannot read property 'get' of undefined in Fuse.Scripting.DiagnosticSubject<FuseJS/Internal/Model.js:135>`

In Fuse 1.6, when including module processed with rollup/webpack, I get the following error:

[Viewport]: Error: TypeError: Cannot read property 'get' of undefined: Uncaught TypeError: Cannot read property 'get' of undefined in Fuse.Scripting.DiagnosticSubject<FuseJS/Internal/Model.js:135>

Same module was working just fine in Fuse 1.5.

I added pre-compiled module into Fuse 1.6 test project to quickly demonstrate the issue in practice, you can check it out at

I haven’t included rollup/webpack config used to generate the module (don’t think it’s relevant in that case), but here’s the source for the module:

Thank you, the issue has been reported.
