Web Reference: 2 days ago · TypeScript infers the return type as Promise even if you don't annotate it, but I recommend being explicit. It makes the contract clear to anyone reading the code. Whenever TypeScript finds an error, it tries to explain what went wrong in as much detail as possible. Because its type system is structural, this often means providing somewhat lengthy descriptions of where it found a problem. If you want something more specific, you will either need to write code to narrow down what type of thing was thrown, or you will need to use a type assertion. Keep in mind that a type assertion is a way to tell typescript "i know more than you do, so don't check my work".
