Activitywatch: Creation of a category with Rule of Type: None throws an exception

[muhdiboy]

Describe the bug

The newly introduced category feature in version 0.8.1 has a bug when creating a new category with no Rules (Type: None).

To Reproduce

Steps to reproduce the behavior:

1. Go to 'Settings'
2. Click on 'Add category'
3. Edit category (click on edit icon on the right hand side)
4. Set 'Type' of 'Rule' in Menu to 'None' and click 'OK'
5. Save
6. Go to 'Activity' and you will see a red banner with following text: "Error: Request failed with status code 400. See dev console (F12) and/or server logs for more info."

Expected behavior

The pregiven categories (e.g. Media or Comms) don't have these issues. I would expect this category to behave like them, just an organizing category.

Possible temporary solution

Problem can be solved by either deleting the whole category (obviously), setting a Rule that doesn't match anything (e.g. some big Hex-Number: "4BAB231F049AEA1D9") or setting a Regex Rule that also won't match anything but is a bit cleverer (e.g. ".^")

Thanks for reporting!

We noticed this ourselves a couple of days ago, and will be fixing it shortly. It might take a couple of weeks until there is a new release with the fix included, but we're on it :)

Great to hear!

As I've noted I have a temporary solution for the meantime.
