After setting the SQLMAP_PATH to /pentest/database/sqlmap, the rhost to my website, and attempting to run, I get the following error "TypeError can't convert nil into String"


Code:
[*] Error: [IP]: TypeError can't convert nil into String[*] Scanned 1 of 2 hosts (050% complete)[*] Error: [IP]: TypeError can't convert nil into String[*] Scanned 2 of 2 hosts (100% complete)[*] Auxiliary module execution completed
Any ideas? I've done the googling and checked metasploit's site, but didn't find a way to correct the issue?
