Getting an error when Installing a Nugget

Hi experts,

I was trying to install an Nugget for navigating from a link in the side panel. I am referring to the documentation given in the below link.

i have created the method zsaplink_installer. when I executed the program it asked me to select the Nugget file which i have selected and executed. At this point it is giving me the below error.

I have tried deleting and reinstalling also. Still it is going for dump.

Please help me in solving the issue.

Thanks and Regards,
