There are two things reported in this bug.
1) Create 4 node mix clusters (6.6.3 and 7.0.2), Try to add a new handler from 6.6.3
In this, the 6.6.3's "Add Function" logic kicks in. This has a broken Add Function logic - Fires an import API asynchronously, disregards the API response totally, adds the function to the browser's list of functions and routes the user to JavaScript code editor. This approach has numerous issues - list will display the function whose import failed, all actions on this function will fail (as it does not actually exist in the backend), the function will disappear once the resync is done etc. The import failure is what Deepika Verma reported in https://issues.couchbase.com/browse/MB-48319.
These were fixed recently in 7.0.2.
2) Create 4 node mix clusters (6.6.3 and 7.0.2), Try to add a new handler from 7.0.2
This is a bug introduced by my fix for the issues listed above. In a mixed mode cluster, the call to retrieve scopes for all buckets fails. A variable that holds a Map of all keyspaces ends up being null - I am missing a null check where I access this Map.
Jeelan Poola: One additional note - I've fixed the null check and push it out. With this, the Add Function dialog will show up. However, as we will not have any scopes / collections in the mixed mode, one cannot actually select a valid keyspace for either "Listen To Location" or "Eventing Storage" to successfully add a function. FYI. Even if one were to be able to select keyspaces, the backend Import call will fail as long as the cluster is in mixed mode.

Thank you Srinivasan Raman! We must fix the 'null' check in 7.0.2, hence I created the backport for 7.0.2 MB-48337.
Sure, Jeelan Poola. Once the code review is complete, I'll push the change to 7.0.2 as well.
Build couchbase-server-7.1.0-1251 contains eventing commit 336b016 with commit message:

Srinivasan Raman Could you please help check this once? I wonder if some UI errors are getting masked
Vikas Chaudhary Could you confirm what behaviour you see on the REST end points?
