I'm using the config file that you have provided as template-
{
"urn":"Container",
"dataset":"temperature.csv",
"queryParameter":"containerA",
"intervalInMilliSeconds":1000,
"resources":[
{
"uri":"temperature",
"contentType":"raw",
"contentTemplate":"${temperature}"
},
{
"uri":"humidity",
"contentType":"raw",
"contentTemplate":"${humidity}"
}
]
}
