Gzip decompression in Edge

[#1]

We have a requirement where we need to decompress gzip string in Apigee Edge before sending it to Target Server.

Consuming app will be sending gzip data but target server doesn't support gzip format. So we need to decompress in Apigee.

How to achieve this ?

I tried using Content-Encoding : gzip and then passed the gzip data. But i am getting following error :

{
  "fault": {
    "faultstring": "Failed to Decompress",
    "detail": {
      "errorcode": "messaging.adaptors.http.DecompressionFailure"
    }
  }
}
