GetInt report an error

[itMuYou]

The int number that I configured in the JSON file but when I get it with GetInt it will say value %!s(float64=20) (float64) is not int

[miladrahimi]

Could you please attach the config file that includes the value you are trying to get?

{
"fault" : {
"host" : "127.0.0.1",
"port" : "6379",
"password" : "",
"database" : 2
},
"upgrade" : {
"host" : "127.0.0.1",
"port" : "6379",
"password" : "",
"database" : 3
}
}

This is my format,I need database to be of type int, but what I actually get is float
