The error "MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error" occurs when Redis tries to save the database in the background but fails.
One of the scenarios where it's known to happen is when redis was recently upgraded by homebrew.
To resolve the issue, ssimply restart your redis instance:
-
On Mac:
brew services restart redis redis-server -
On Linux:
sudo service redis restart sudo systemctl restart redis sudo service redis-server restart sudo systemctl restart redis-server.service
