The issue you’re encountering has to do with the format of the ‘app_instance_id’ you’re attempting to retrieve from Firebase. This ID needs to be a 32-digit hexadecimal number, but the ID you’re receiving is a 22-digit number. Firebase’s ‘installations’ service provides an ID, but it seems that this ID isn’t suitable for use as an ‘app_instance_id’ in the ga4 API. You need to find a different method to obtain the ‘app_instance_id’. The Firebase SDK documentation or Google Analytics documentation may have more information on how you can correctly obtain this ID.

The issue you’re experiencing might be due to Google Analytics not being able to instantaneously reflect changes made in your customized reports. When you add a new dimension like “Link URL”, the system might need some time to gather and reflect that data. This is more evident if your website has high traffic or numerous Landing Pages. It might be a good idea indeed to wait for a day or two and then check the report again. If the issue still persists, it might be worth checking whether you’ve correctly set the parameters for the inclusion of the “Link URL”. The fact that you’re seeing aggregated data suggests that data is being collected, but perhaps not displaying as expected due to how the dimension has been added or defined.

Hey, I get your point with the whole BETA thing, it sure does add a spice of thrill, doesn’t it? But you know what, that’s technology for you, always evolving and improving. So, yeah, the API is still in beta, no doubt about that. There’s no other Google-sanctioned way currently to extract data from a GA4 account. So, let’s ride this wave together, my friend! And remember, sometimes trying out something different (even something in BETA) is what sparks brilliant solutions. Hope everything goes smoothly with your app!

You’re encountering an error because the “minute” dimension and the “activeUsers” metric are not compatible. Some metrics can only be used with specific dimensions. “minute” is a dimension used to specify time, but “activeUsers” does not make sense within the scope of minutes because it generally measures over longer periods (e.g., sessions or days). You’ll need to modify your request so that the dimensions and metrics are compatible and make sense within the same scope. You can explore compatible dimensions and metrics on the GA DevTools website that your grpc_message linked to.

Google Analytics 4 (GA4) has been designed as an entirely new version with a different set of advanced features aimed at providing an improved user experience, compared to Universal Analytics (UA). It is oriented towards offering more insightful data analytics based on user-centric measurement, superior privacy protection, advanced AI, and complete cross-platform tracking. As part of this upgrade, Google might have decided to revamp or eliminate certain previous features based on user-data analysis, feedback, and the latest market trends. Therefore, it is not uncommon for a few features that existed in UA to not be available in GA4. It’s better to consider GA4 as a separate entity from UA rather than a simple upgrade. Google is also constantly updating GA4, so some missing features might be added in the future.
