Issue Report: Private key must be less than the curve order

When i enter the document or sheets, a blank page opens.
The JS console gives an error: Error: “Private key must be less than the curve order”

This happened to me too. Opening Graphite from my default browser fixed the problem.
It might be a good idea to open an issue in their github repo: https://github.com/Graphite-Docs/graphite

This is caused by this issue:

The issue is that the app has to initiate and complete the authentication process within the same browser context. A patch is in the works to improve the error handling in this scenario.
