    Dear PWA for WP team,

    Thank you for creating such a useful plugin.

    I wanted to use it, but I encountered a problem with pwa-register-sw.js.

    A global variable named “messaging” seems to be declared twice in line 3.
    I tried to replace it with :
    if (typeof messaging === “undefined”) { const messaging = firebase.messaging(); }
    and it seemed to work for me.

    I understand that this may not be your fault, but I would appreciate it if you could take this case into account.

    Thank you in advance.

    Thank you for your response.

    The error message on Chrome is:
    Uncaught SyntaxError: Identifier 'messaging' has already been declared (at pwa-register-sw-1.js?ver=1.7.57:1:1)

    My Software Versions are:
    WordPress 6.1.1
    PWA plugin 1.7.57

    I found another solution. I commented out line 3: const messaging = firebase.messaging; and replaced all ‘messaging’ in pwa-register-sw-1.js with ‘firebase.messaging’.

    I think the pwa-register-sw-1.js is fine on its own, but another plugin is using the global variable ‘messaging’ as ‘const’ in another .js file, and conflicts with the definition in pwa-register-sw-1.js as the error.
