---------------------------------
Summary: Function Execution Through REST API Limitation
Key: GEODE-7259
URL: https://issues.apache.org/jira/browse/GEODE-7259
Project: Geode
Issue Type: Bug
Components: docs, rest (dev)
Reporter: Juan Ramos
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}
