Where can I find the API JSON response to get all issues assigned to a user ?

[Rahim T_S]

I was working with https://www.npmjs.com/package/jira-client to create a jira automation utiltiy

This wrapper has a method to get all issues assigned to a user

     * @param username - username of user to search for

     * @param open - determines if only open issues should be returned

     */

    getUsersIssues(username: string, open: boolean): Promise<JiraApi.JsonResponse>;

but the response when printed to the console is [object, object] 

Where can I find the JSON response to this method so that I can access the data inside this ?

Thank you
