Cannot save to HAT

If I click on Save All Configurations I got Couldn’t write configurations to the HAT. Please save configurations again." on the docker container I see

Exception in thread Thread-20:
Traceback (most recent call last):
File "/usr/local/lib/python3.6/", line 916, in _bootstrap_inner

KeyError: ''

I guess it is related with scheduling entries!

Current firmware version is 0.3.0 and
Current software version is 0.2.1

How can I save the configuration to HAT?

I have the same current “ware” versions. I have only one Pi and I save test configurations under “device” and “save.” The configuration writes to HAT and is saved but sometimes the event does not occur. I tried testing configurations under “fleet” where I have only the one device and this is where I get writing to HAT errors.This area also advises to save configuration with a notification as when configuring under “device” does not advise to save.
