@sommersoft speculates that this prevents only release of the community bundle, not the adafruit bundle.

The first occurrence of the error shows that the Adafruit bundle is successfully updated, while the error occurs on the Community bundle: https://github.com/adafruit/adabot/runs/969756000?check_suite_focus=true#step:8:1

Adafruit_CircuitPython_Bundle
Releasing 20200811
New libraries: [matrixportal](https://github.com/adafruit/Adafruit_CircuitPython_MatrixPortal/releases/1.0.0)
Updated libraries: [bitmapsaver](https://github.com/adafruit/Adafruit_CircuitPython_BitmapSaver/releases/1.1.2), [rsa](https://github.com/adafruit/Adafruit_CircuitPython_RSA/releases/1.2.0)

As always, thank you to all of our contributors: @makermelissa, @dherrada, @brentru, @***, @kattni, @FoamyGuy, @tannewt

--------------------------

The libraries in each release are compiled for all recent major versions of CircuitPython. Please download the one that matches the major version of your CircuitPython. For example, if you are running 4.0.0 you should download the `4.x` bundle.

To install, simply download the matching zip file, unzip it, and selectively copy the libraries you would like to install into the lib folder on your CIRCUITPY drive. This is especially important for non-express boards such as the [Trinket M0](https://www.adafruit.com/product/3500), [Gemma M0](https://www.adafruit.com/product/3501) and [Feather M0 Basic](https://www.adafruit.com/product/2772).

Of the recent PR merges, none should be affecting this so it'll take some troubleshooting.

Looks like the cause is a malformed URL in the .gitmodules for the Community bundle:

(.env) ~/Dev/adabot/adabot:$> python -m adabot.circuitpython_bundle
CircuitPython_Community_Bundle
https://api.github.com/repos/Pimoroni_CircuitPython_LTR559//commits/03cba545e6d2a6079e2fe29b2f791818f65efe36
  repo: Pimoroni_CircuitPython_LTR559/
  error: KeyError: 'author' 
  api response: {'message': 'Not Found', 'documentation_url': 'https://docs.github.com/rest'}

I'll get a PR in to fix the .gitmodules entry.
