Datagrid ERROR CE6093??

Hello. I recently updated the data widgets in my app, and I got this error as a result. I have been unable to fix it for a while now and am hoping that someone here can point me in the right direction. I have tried a few options for correcting this but none seem to work so far.

That should be defined in the Atlas Core module. Do you have that installed? If you don’t, you’d need to create a variable called $form-input-border-color elsewhere in your theme. This link shows you how to add a custom variable if you are unsure how to do that.
