Syntax error in config

[tonizombie]

Ive added this part into the config
{
module: "MMM-LocalTemperature",
position: "top_left", // Only add a position if you want this module to display the data
header: "Room Temperature",
config: {
sensorPin: 22, // For GPIO 22
...
// See below for more Configuration Options
}
},
However when starting or running config:check it gives an error
" [ERROR] Line 174 column 3: Parsing error: Unexpected token { "
Line 174 being the first { at the very start
