Errors in node_modules/sprotty when extending from sprotty class

[glsp-bot]

I want to extend from EditLabelUI (inclient\node_modules\sprotty\src\features\edit\edit-label-ui.ts) to implement autocomplete functionality. When Extending from EditLabelUI I get a lot of errors when compiling which are all located in the sprotty code. Becuase of that the application does not work anymore.

Code:

Error messages:

Any experiences on how to properly extend functionality to node_modules?

Looks to me like your import statement is wrong. Should be import {EditLabelUI} from 'sprotty/**lib**/features/... . (edit-label-ui is also added to the index so you can simply import from 'sprotty/lib' as well)
