Hello Everyone,
As you can already read in my title I have a Problem with the Bundler.
I used the Liferay-js generator for creating a simple Javascript project. The only libary I want to add is called formiojs.
As far as I can tell the problem is that the bundler does not find the node modules lay in @Types.

This is the error I get if I try to load it as a portlet on the portal:

Error: "The following problems where detected while resolving modules: · Missing dependency ':ERROR:Missing version constraints for formionpm$stream in package.json of formionpm$node-fetch@2.6.0' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency ':ERROR:Missing version constraints for formionpm$http in package.json of formionpm$node-fetch@2.6.0' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency ':ERRORpackage formionpm$url which is a dependency of formionpm$node-fetch@2.6.0 is not deployed in the server' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency ':ERROR:Missing version constraints for formionpm$https in package.json of formionpm$node-fetch@2.6.0' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency ':ERROR:Missing version constraints for formionpm$zlib in package.json of formionpm$node-fetch@2.6.0' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency ':ERROR:Missing version constraints for formionpm$encoding in package.json of formionpm$node-fetch@2.6.0' of 'formionpm$node-fetch@2.6.0/lib/index' · Missing dependency 'formionpm$dragula@3.7.2/dist/classes' of 'formionpm$dragula@3.7.2/dist/dragula' · Missing dependency 'formionpm$dragula@3.7.2/dist/debounce' of 'formionpm$dragula@3.7.2/dist/dragula' · Missing dependency 'formionpm$dragula@3.7.2/dist/eventmap' of 'formionpm$dragula@3.7.2/dist/dragula'" 

If I start the test server everythings works. I tried to add Typescript compiler as well but had no luck with it.

Here is my package.json:

Thank you all in advance and tell me if I can add additional information to solve the problem.
