I'm rather new to React and now trying to fix an error that occurs at runtime due to a new version of prosemirror.model in our artifactory. The new version is 1.18.1, the old version that works was 1.16.1.

Loading the page gives the following error in console:

Uncaught TypeError: prosemirror_model__WEBPACK_IMPORTED_MODULE_0__.Schema is not a constructor

Code line that breaks:

export const schema = new Schema({ nodes, marks });

I've tried to find the code to create the Schema instance without constructor, but couldn't identify it. Even the prosemirror guide and code themselves use the constructor to create a Schema object, so I'm quite confused about this. Anyone an idea how to solve this?
