Cannot find name 'Headers', 'RequestInit', 'Response'

I updated my nativescript from the 2.5.2 to the 3.0.3. And suddenly when I try to run the app I get the following errors:

node_modules/tns-core-modules/tns-core-modules.d.ts(17,27): errorTS2304: Cannot find name 'Headers'.

node_modules/tns-core-modules/tns-core-modules.d.ts(19,44): errorTS2304: Cannot find name 'RequestInit'.

node_modules/tns-core-modules/tns-core-modules.d.ts(19,66): errorTS2304: Cannot find name 'Response'.

I don't understand why, because I think I'm not using this modules in my project.

Thanks! :)
