dataframe - Multiple coordinates get_elev_point in R

Question

I hava another geodata question. I am trying to access the elevation data for specific points with the get_elev_point ()

I have about 160 points that I would like to get the elevation data for, so I would like to not do it one by one but I do not know how to retrieve them all at once.

I have made a data.frame of all my points where the first column x is longitude and the second column y is latitude and these are the only data in the data.frame.

> elevationpoints <-get_elev_point(locations = pontok_df, units="meters", prj = ll_prj, src = "aws")

Error in seq.default(from = ceiling(min_tile[2]), to =
floor(max_tile[2])) :    'to' must be a finite number In addition:
Warning message: In log(tan(lat_rad) + (1/cos(lat_rad))) : NaNs
produced

But it does not seem to yield any results. Could you please help me? Much appreciated!
