The error messages you are seeing occur when the code tries to read or utilize a property or method from an undefined object in JavaScript. ‘TypeError: Cannot read properties of undefined (reading ‘id’)’ implies that the object that this ‘id’ property is tied to is undefined. Similarly, ‘o is not a function’ means that the program has attempted to invoke an entity ‘o’ that has not been specified as a function.
This could be caused by several factors – firstly, it could be that you have a typo or error in your code that causes certain objects or functions to be undefined. Secondly, it could be that your Firebase implementation or the upgrade to GoogleAnalytics4 is not properly configured, making the references to these entities invalid.
In order to diagnose and fix the problem, here is what I suggest:
1. Double-check your code for any typos or errors, especially those related to the undefined entities.
2. Review your Firebase setup and GoogleAnalytics4 upgrade process. Make sure the configurations are correct according to the official documentation.
3. Try to isolate the issue. Run various parts of your application separately and find out which specific part is causing these errors to occur. This should help you narrow down your search for the error’s cause.Also, make sure to fully understand JavaScript Promises and async/await usage for Firebase since this is also a common place where errors occur.
