[Firebase Analytics Plugin] ODC Firebase Analytics Plugin – How to clear UserId with setUserId(null)?

Esma Kovacevic

Question

Using the Firebase Analytics Plugin in ODC and need to implement Firebase User-ID.
Setting the User-ID works correctly:SetUserId(user_key)
The issue is on logout.
Firebase requires:setUserId(null)to clear the current User-ID.
However, the ODC plugin exposes SetUserId with a mandatory Text input, so I cannot pass a real null value.
tested:"null", nullidentifer(),"" → Firebase treats it as a value, not as null"" → the previous User-ID remains
verified this in Firebase DebugView, where the previous user_id was still attached to an event after logout.
Is there a supported way in ODC to call setUserId(null) with this plugin?

Plugin version: Firebase Analytics Plugin ODC 1.7.1.
