Hi,

Then Please uninstall your current wkhtmltopdf package and install it again.

You can use the below code:

sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb

sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb

sudo apt install -f

Can you please try it with version 0.12.5.

Hope it helps
