Reading resource file issue

Hi. I was making a language system for my project and it threw a NullPointerException. Every solution on the internet did not work. For some reason, the code that reads the image on the same resources folder did work. So, heres the code:

private String getLocalizedJson() throws IOException {
        return new String(getClass().getClassLoader().getResourceAsStream("/resources/localizedtexts.json").readAllBytes());
    }

private String getLocalizedJson() throws IOException {
        return new String(getClass().getClassLoader().getResourceAsStream("/resources/localizedtexts.json").readAllBytes());
    }

Stack trace:

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.io.InputStream.readAllBytes()" because the return value of "java.lang.ClassLoader.getResourceAsStream(String)" is null
    at com.mokkachocolata.util.Localization.getLocalizedJson(Localization.java:25)
    at com.mokkachocolata.util.Localization.getLocalizedText(Localization.java:50)
    at com.mokkachocolata.project.adbgui.MainFrame.init(MainFrame.java:56)

umm i dont know but the app icon displays correctly though like

setIconImage(Toolkit.getDefaultToolkit().
          getImage(this.getClass().getResource("/resources/appicon.png")));

setIconImage(Toolkit.getDefaultToolkit().
          getImage(this.getClass().getResource("/resources/appicon.png")));
