> Function execution through the {{REST API}} doesn't support nested collections as part of the parameters, this is an undocumented limitation.
> We basically try to convert the {{JSON}} parameters into a {{Map}} and afterwards, based on the {{Map}} contents and the {{@type}} value within the JSON string, convert that into the actual {{Object[]}} parameters expected by the function. If any of those objects contain an inner collection ([] as JSON) or object ({} as JSON), the initial parsing will always fail:
> {code:title=AbstractBaseController.java|borderStyle=solid}
> private Map<?, ?> convertJsonToMap(final String jsonString) {
>     Map<String, String> map = new HashMap<String, String>();
>     // convert JSON string to Map
>     try {
>       map = objectMapper.readValue(jsonString, new TypeReference<HashMap<String, String>>() {});
>     } catch (JsonParseException e) {
>       throw new MalformedJsonException(
>           "Bind params specified as JSON document in the request is incorrect!", e);
>     } catch (JsonMappingException e) {
>       throw new MalformedJsonException(
>           "Server unable to process bind params specified as JSON document in the request!", e);
>     } catch (IOException e) {
>       throw new GemfireRestException("Server has encountered error while process this request!", e);
>     }
>     return map;
>   }
> {code}
