"TypeError: null is not an object" on .js file with Expo and TS project

[RodrigoGCoelhoo]

Hey guys. Currently I'm developing a project using React Native with Expo and TypeScript. Since there is no support for typescript, I'm trying to use the package on a .JS file, but the environment doesn't recognize the package. Because of this, everything I try to do with the SerialPortAPI class doesn't work. I'll list here my environment settings and the erros I'm stuck with.

package.json

Code executed

Error

tsconfig.json

Saddly no, I've tried many things but nothing worked.
