Error Message "! Aesthetics must be either length 1 or the same as the data (456): label "

I am a newbie to R. I am trying to show two ggplots on one screen using the patchwork package with the following code and I am getting the above error. I have tried resolving the error unsuccessfully, I can resolve the error for "fill" aesthetic only. Kindly assist.
