TypeError: dailyData[currentIndex][PropertyName.START_INDEX.value] is NoneType (ran by Home Assistant)

[C-Duv]

Hello, I have an issue running the library. I am not using it directly: I am running it via home-assistant-gazpar but I think the issue comes from the library so I am posting it there.

Home Assistant logs shows

I guess something is wrong with the obtained data but I feel library should not "crash" like that.

Note: My home-assistant-gazpar's scan_interval is set to 08:00:00.

By the look of ssenart/home-assistant-gazpar#72 I guess you reproduced the bug?

[ssenart]

Yes, thanks.

The bug was triggered by empty measures where we expect some.

Anyway, I fix that case in: https://github.com/ssenart/home-assistant-gazpar/releases/tag/1.3.11-alpha.0

And in the meantime, GrDF republished clean data. The problem should be fixed on your side as well without doing anything. Do you confirm ?

[C-Duv]

Great, I'll tell you tomorrow then, once the update process occurs in Home Assistant.

[C-Duv]

Yes, it does not fail anymore: I do have data now.

Only error I sometimes get in the logs are:

2024-12-15 06:14:28.993 ERROR (SyncWorker_0) [pygazpar.datasource] An error occurred while loading data. Retry in 3 seconds.

But:

• The data from yesterday are not available (but I think I've read something about this in an issue)
• Sometime there are negative reading (decreasing the consumption)
