NgRX effects - Type 'Observable' is not assignable to type 'Observable'

Question

While working with NgRX 8 my colleagues and me are frequently facing a weird error message when implementing the effects.

Type \'Observable

Answer 1

In my case, I used a lodash operator inside one of the rxjs operators. Turned out, I didn't have @types/lodash. After npm i -D @types/lodash, my problem was solved.
