Unclear error when using input data.frame of more than 2 columns

Hi TNRS maintainers 👋

I really like the feature that let's the user submit a data.frame to the TNRS() function so that they can be easily referred in other contexts. However, I had a 3 columns data.frame that also included some additional info on the names, then the function output a strange error. I perfectly understand why TNRS() would only accept 2 columns data.frame and I have an easy fix for that, but maybe the error message could be clearer.

reprex:
