Application Failed to Start

I have the following error when I tried to deploy my app:
Attaching package: ‘DT’

The following objects are masked from ‘package:shiny’:

dataTableOutput, renderDataTable

I've seen other posts about this issue with loaded packages but can't really understand how to solve my problem.

Is anyone knowledgable about the topic and can help this Shiny newbie out please? :slight_smile:

Thanks in advance!!
