Force a reindex, submit a diagnostic and provide the id number to Sonos support, they can see details we users can’t see.
Thanks! It turns out that apps on Mac are nowadays forced to ask disk-access permission. Sonos app never did as far as I’m concerned… It turns out that was the problem: although the music is a normal directory (i.e. not on a USB drive), I tried this, which solved the issue:

The problem is that I had to grant access to my full disk whereas there is no reason for Sonos app to access more than those directories I configure for it… How should I communicate with Sonos about this ? Also via a ticket to Sonos support ? NB: I can’t imagine why there are not already zillions of tickets about this & a software update to solve it...
This solved the problem for me as well, allowing “full disk access” to the “Sonos Library Server” in Catalina’s Security and Privacy settings as outlined in the article: https://support.sonos.com/s/article/4808?language=en_US
I did have to dig a bit to find this solution so I’m just adding this comment with some keywords to help others find the solution.
Situation: after upgrading MacOS to Catalina, the Sonos desktop app was no longer able to see the external hard drive containing my music files. It was working immediately prior to the upgrade, so I’m sure that was the cause of the issue.
Entering in the path to the folder would generate an error 1002 when attempting to complete, both on the mobile app and desktop. As other users mentioned, the entered folder location of “/Volumes/Drive/Music” appears as “//Mac/Music” in the app, which I thought was the issue but wasn’t.
I suspected that it was a security setting preventing the process from completing and specifically looked in the System Preferences “Security & Privacy” section, even adding the Sonos app to the list of “Full Disk Access” apps. The key here was that I didn’t notice the “Sonos Library Server” app there, it doesn’t have the Sonos app icon! Anyway that wrapped it up. Hope this helps!
