Error: '<=' not supported between instances of 'NoneType' and 'datetime.datetime'

[RichardHyde]

Since updating to the latest build I've been getting an error '<=' not supported between instances of 'NoneType' and 'datetime.datetime' which wasn't happening with the v0.13.6 release.

I've gotten the error from two sources, Linus Tech Tips and MKBHD, and seems to be happening when running the sync.tasks.index_source_task task.

The error message from the background_task table is

Traceback (most recent call last):

Let me know if you need any additional info, or want me to try something

Thanks for the issue! Again looks like this was introduced in a recent feature update and the above commit should fix it. It'll be available in :latest once the image builds. Feel free to open more issues if you encounter any more bugs, reports like this are most helpful.
