Pass column -Value pair as stringifyJson in Request body

Hi,

I am trying to consume CDS entity from Postman.

One of the parameters is fieldValueMapping which expects the column and its value as stringifiedJson in request body.

I created a pre-requisite script

And passed the variable in the request body

I do not have much experience in using postman , need your guidance in passing the parameter properly.

try adding double quotes:

{
"blabla":"blabla",
"fieldValueMapping":"{{fieldMappingAsJsonString}}"
}

When you pass string to json it should be enclosed with double quotes
