SAP NetWeaver Gateway Batch Services

Hi All,

I just need small help regarding GateWay Services for Batch-Retrieval Read (POST/PUT).

In Rest-Client i'm giving my service URL following $batch& those Header Details--

Authorization: Basic c3VtYW4ucGFkaWExMjM=

x-csrf-token: U1UjqYUouCRIoRTmaF8qOQ==

Content-Type: multipart/mixed; boundary=batch

And in BODY, i'm giving

--batch

Content-Type: application/http

Content-Type: application/json

content-length: 54768

Content-Transfer-Encoding: binary

GET WBSCollection(PROJECT_ID eq '12345') &$format=json   http/1.1

--batch

when i'm sending the request getting status message i.e

202 Accepted i.e correct

but in Response TAB getting this message

Response does not contain any data.

i checked in my RFC or even Class Label everything is working fine but not getting

any data from rest client ?
