LuciferYang opened a new issue, #9766:
URL: https://github.com/apache/paimon/issues/9766
### Bug description
The public `DataTypeJsonParser.parseDataField(JsonNode)` entry passes a null
field counter into the private overload. Parsing a field json without an `"id"`
node therefore throws a bare `NullPointerException` from the counter increment,
although the sibling public `parseDataType(JsonNode)` entry auto-assigns ids
for exactly such input.
Reachable from the `create function` procedures: Flink/Spark
`CreateFunctionProcedure` → `ParameterUtils.parseDataFieldArray` →
`DataTypeJsonParser.parseDataField` on user-provided
`input_params`/`return_params` json, e.g. `[{"name":"x","type":"INT"}]` (no
`"id"`).
### Expected behavior
Mirror `parseDataType`: auto-assign the id (or otherwise fail with a clear
message) instead of an NPE.
