Device dependencies could not be retrieved error

I’m trying to set up device dependencies to reduce the number of alerts I get when my router goes down. When I click “Device Dependencies” in the Devices menu (I don’t have any yet), it produces an error “Device dependencies could not be retrieved from the database.” I’m assuming something didn’t happen quite right on install, but I don’t think I missed any steps. When I click the “Manage Dependencies”, I get the dialog but it doesn’t let me put anything in the boxes (as in the YouTube video). Suggestions as to how to get this started?

validate.php output:


Component Version
LibreNMS 21.1.0-28-gb86dbcf69
DB Schema 2021_02_09_084318_remove_perf_times (199)
PHP 7.4.3
Python 3.8.5
MySQL 10.3.25-MariaDB-0ubuntu0.20.04.1
RRDTool 1.7.2


[OK] Composer Version: 2.0.9
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

I can add that I think I’ve now managed to create dependencies through the individual devices, but the “Manage dependencies” option still gives the same error. I have not tried shutting down a parent to see if it behaves correctly yet.
