IndexError in DEBUG logging of Proposed optimization window

[luuuis]

Describe the bug Upon upgrade to 0.6.6 EMHASS stopped working in Home Assistant due to the following error.

2024-02-22 15:37:00,247 - web_server - ERROR - Exception on /action/dayahead-optim [POST]

IndexError: list index out of range

To Reproduce

1. Do not configure def_start_timestep or def_end_timestep in YAML,
2. Send a dayahead-optim request without providing either def_start_timestep or def_end_timestep in the payload.

Expected behavior Configurations that were previously working should continue to work, especially for optional parameters. Alternatively, if these parameters are required then they should be validated and an appropriate error message issued.

Additional context Add any other context about the problem here.

Do not configure def_start_timestep or def_end_timestep in YAML

Just configure these. They just should have the same length as the number of deferrable loads.

This was an unexpected breaking change, so that's why no warning was issued. But the solution is easy and the error messages were improved after this.

Closing.

Yes, I configured locally once I figured out what was the cause. Just looking to avoid this for others who upgrade, glad it's fixed in later versions. 👍
