Extract variables policy is not working as expected.

[arunprasath25]

Tried to search and extract few elements from JSON payload using Extract Variables policy. Responded no values with 200 response.

FYI: tried response.content value for the <Source> tag. @Anil Sagar @ Google @Dino-at-Google @Siddharth Barahalikar

</AssignMessage>

Expected response

{
 "name": "["Rahul3210"]",
 "salary": "["30000"]"
}

Actual Response

{
 "name": " ",
 "salary": ""
}
