eolivelli opened a new pull request #8883:
URL: https://github.com/apache/pulsar/pull/8883
Describe the bug
It looks like GenericJsonReader is not handling correctly null values
This is a reproducer:
byte[] json = "{\"somefield\":null}".getBytes();
GenericJsonRecord record =
new GenericJsonReader(Collections.singletonList(new
Field("somefield", 0)))
.read(json, 0, json.length);
assert record.getJsonNode().get("somefield").isNull();
assert "null".equals(record.getField("somefield"));
assert record.getField("somefield") != null;
Expected behavior
The null value is not converted to a string, but it is still a null value
Additional context
The problem affects Pulsar Functions/Pulsar IO
Fixes #8882
