Bug Report

In javascript when defining a callback and applying the type to a function which doesn't return anything, an error of type TS2355 is raised. And this is the correct behavior.

However tsc fails to show both the file and the line number of the problem. This can be quite annoying when dealing with a very big project :D

💻 Code

/**
 * @callback Func
 * @returns {Promise<number>}
 */

/** @type {Func} */
function test() {
  console.log("Nope");
}

🙁 Actual behavior

• The error TS2355 is correctly detected but the line number (and also the file when dealing with a project) is not reported

🙂 Expected behavior

• The tsc compiler should correctly report both line number and file
