I am getting the HttpMessageNotWritableException when I try to execute the following code:
def rest = new RestBuilder(connectTimeout:10000, readTimeout:20000)
def resp = rest.post("http://requestb.in/1mhfid91"){
json {
name = "test-group"
description = "A temporary test group"
}
}
Please suggest if I am missing something.
Here is the Exception message:
org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: (was java.lang.NullPointerException) (through reference chain: grails.converters.JSON["depth"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: grails.converters.JSON["depth"])
