I have a Visualforce Lightning Out page that’s rendering some
<lightning:input type="date">elements. Since the Winter ’19 release in the dev sandbox I’m working in, whenever I select a date from the calendar that appears when focusing the element, I get the following error:
Has anyone else seen this behavior? Is it a Winter ’19 bug? Is there any corresponding Known Issue?
The issue previously could be reproduced using the following steps:
- Create a lightning:recordForm component or a lightning:input component for entering a date.
- Edit the record, and select a new date.
These steps would result in the following error:
This page has an error. You might just need to refresh it. First, would you give us some details? (We’re reporting this as error ID: XXXXXXXXXX)
