When deploying an app I got Warning in FUN(X[[i]]) , but still deploy's

shiny shinyapps.io

In the last weeks I'm getting the following message

It stills deploys, with no general problems. But still it makes me nervous since I didn't get that message before

I have dbConnect version 1.0.
R version 3.6.2
Rsconnect 0.8.16
