Passing blank values in parameters of type "C"

[rpuranda-tibco]

Want to pass a single character as space in input params. Something like this: c, _ := gorfc.ConnectionFromParams(abapSystem()) params := map[string]interface{}{ "CALL_RFC":" ", } r, e := c.Call("Z_ALLDATATYPE_CLIENT_TEST1", params) if e != nil { fmt.Println("Error is:", e) } Here after Call, no error is returned and exit status 0xc0000374. Can you suggest what could be the issue?
