Customer Impact
A user reported this issue here - #7595. I think this is a very rare race condition between awaiting a task then creating the
EditContext, and parameters being set. If parameters are set before the context is created then it errors.Although this is the first reported instance of the error, it might have impacted more customers. The fix is simple: refresh the browser. Customers might not have taken the time to report the problem after it went away.
Testing
Unit test. Manual testing isn't really possible as it depends on a race condition.
Risk
Low
Regression?
No, not a 9.1 regression. This bug has been here since 8.0.
