How to resolve Error in resolver stop on character in R

I have no sample data so pardon me. However, I am just looking for some basic information on this error. This only started occurring when I installed R 4.2.1. The full error is that the following rows do not exist. The data frame that the item is drawing from shows data when I go to the environment. Also, it occurs when I knit the document but not when I run the individual code chunk. The code chunk where this error occurs runs fine when I click the green triangle to the right.

Has anyone ever encountered this error? If so, what did you do to resolve it?

This suggests you are not including code to define the mentioned data frame in the Rmd file itself, or at least the code chunk that contains the data frame definition is not being executed. If this doesn't solve your problem, I strongly recommend you put together a reproducible example, even with made-up data.
