    I am using the latest DFFS (April 15, 2018) in SharePoint 2013 on prem to create a new cascading dropdown field. I don’t have any custom JS, and just a simple two column cascade.

    When I set the parent column to a known value in the lookup list, there is no response and this error in the console:

    TypeError: a is undefined

    I’ve never had an issue with this setup before, so it makes me think its related to the new update. Any thoughts?

    Sorry about that – could you please send me a screenshot of the error message in the console?

    If you could use the Chrome browser and click the link on the error to highlight the section in the code where the error originates from I’ll get it fixed.
