Error Section overlapped PageFooter Section

Problem

I got this error when working on a custom salesinvoice report, "Section overlapped pageFooter section (maybe because the section is too high)". This was coming only for reports which were having high number of invoice lines in our case more than 12.

Solution:

After some investigation, it was resolved by adjusting the height of the first footer section and the last body section (which was just above the first footer).
