Can't open thermostat scheduler

When I try to open the thermostat scheduler for my Rheem water heater, I am getting the following error.

This is what shows in the logs.

This is on a C5 currently running 2.3.4.119

The scheduler seems to still need working and setting the temperature. It just appears that I can't edit it. Wondering if there is a way to fix this without removing and re-adding the app so I don't lose my scheduler settings.

Then put this string in the command box for setSupportedThermostatModes ["auto","off","heat","emergency heat","cool"] and hit the command button. Then put this string in the setSupportedThe…

You only need to fix supportedThermostatModes (not both), and it should be ["off","heat"]
