Postman collection json export file is empty

Hi,
I’m able to export my postman collection but the export json file that is created by postman client does not have any info.

all the individual request that are a part of collection appear like this:-

{
“name”: “FindPrice”,
“request”: {
“method”: “GET”,
“header”: ,
“url”: {
“raw”: “”
}
},
“response”:
},
