Issues with plotting s5p data using Cartopy

So I wrote this code to visualise the S5p data as you guys can see. I am getting these weird warnings due to which the plot that is being formed is not very accurate. By accurate I mean that the plot comes out to be fine sometimes and other times it just doesn’t show up. It is hard to explain. If anyone can see this code and guide me on how to eradicate these errors, it would be very helpful!
