Short summary of your issue

I have a function that ESDoc tries to infer the data type it returns, but it does so incorrectly.

Input data for reproducing

Codes

    function example(args) {
        const errorMessage = {
            get args() {
                return 'args should be valid';
            }
        };

        if (args == null) {
            throw Error(errorMessage.args);
        }

        // ....
    }

Output data

It produces documentation with the wrong data type as the return value from the example function. The example function as you can see above, returns undefined

but ESDocs says it returns string because it's inferring it wrongly.

Your environment

• OS type and version: Mac
• Node.js version: v10.16.3
• ESDoc version: v1.1.0
