Error in seq.int(0, to0 - from, by) : 'to' must be a finite number. What should I do now?

Question

I am trying to plot a summary plot for air pollution data but I'm facing this issue

Error in seq.int(0, to0 - from, by) : 'to' must be a finite number
In addition: Warning messages:
1: Unknown or uninitialised column: `date`. 
2: Unknown or uninitialised column: `date`. 
3: Unknown or uninitialised column: `date`. 
4: In min.default(numeric(0), na.rm = TRUE) :
  no non-missing arguments to min; returning Inf
5: In max.default(numeric(0), na.rm = TRUE) :
  no non-missing arguments to max; returning -Inf

My code:

gum <- read_xls("Gummidipoondi Daily average from 2018 to Sep.2021.xls") 
summaryPlot(gum)
