Error on select data for custom picker field

[Harald Hiebl]

Hi,

I have configured a csutom picker field for data from ServiceNow, but on loading options I get following error:

Error searching: java.lang.UnsupportedOperationException 

java.lang.UnsupportedOperationException

	at org.codehaus.groovy.runtime.ConvertedMap.invokeCustom(ConvertedMap.java:52)
	at org.codehaus.groovy.runtime.ConversionHandler.invoke(ConversionHandler.java:113)
	at jdk.proxy1/jdk.proxy1.$Proxy5118.isEmpty(Unknown Source)

My code for the field is:

HTTPBuilder getHttpBuilder() {

    new HTTPBuilder("https://xxx.com"

    )

}

search = {

    HttpBuilder.request(Method.GET, ContentType.JSON) {

        headers.Accecpt = 'application/json'

        headers."x-sn-apikey" =  "<TOKEN>"

        uri.path = "/api/now/v2/table/cmdb_ci_service_business"

        uri.query = [fields: 'sys_id, name']

    }

}

toOption = { Map<String, String> map, Closure<String> highlight ->  

    new PickerOption(        

        value: map.sys_id,

        label: map.name,    

        html: highlight(map.sys_id, false)

    )

}

Any idea, why the json object can not be converted to a map?

If I create a separate output for the http request, all data are available:

def output = HttpBuilder.request(Method.GET, ContentType.JSON) {

    headers.Accecpt = 'application/json'

    headers."x-sn-apikey" =  "<TOKEN>"

    uri.path = "/api/now/v2/table/cmdb_ci_service_business"

    uri.query = [fields: 'sys_id, name']      

    response.failure = { null }

}

def bsNumber = output["result"]*."number"

def bsName = output["result"]*."name"

def bsSys = output["result"]*."sys_id"

log.info(bsNumber)

log.info(bsName)

log.info(bsSys)
