### Purpose close #9766 The public `DataTypeJsonParser.parseDataField(JsonNode)` entry passed a null field counter, so a field json without an `"id"` node threw a bare NPE — while the sibling public `parseDataType` entry auto-assigns ids for exactly such input. This mirrors that behavior: a fresh counter is passed, missing ids auto-assign from 0, explicit ids keep working, and the private overload's partial-id `checkState` is unchanged. Reachable from the `create function` procedures via `ParameterUtils.parseDataFieldArray` on user-provided parameter json. ### Tests New `DataTypeJsonParserTest`: id-less field auto-assigns 0 (RED on master — NPE), explicit id preserved, nested ROW auto-assigns sequentially. ### API and Format No behavior change for previously-working inputs (all-explicit-id json never touches the counter). Previously-crashing id-less json now parses with an auto-assigned id. ### Documentation None. -- This is an automated message from the Apache Git Service.
