Claus Ibsen created CAMEL-26299:
-----------------------------------
Summary: camel-azure-eventgrid - every send fails with a
NullPointerException: the CloudEvent is built without a data format
Key: CAMEL-26299
URL: https://issues.apache.org/jira/browse/CAMEL-26299
Project: Camel
Issue Type: Bug
Components: camel-azure
Reporter: Claus Ibsen
Fix For: 4.24.0
The producer builds each event with
{code:java}
new CloudEvent("/camel", eventType, BinaryData.fromObject(data), null, null)
{code}
azure-core (1.57.0 on main) requires the format when there is data, so every
send fails before it reaches Azure:
{noformat}
java.lang.NullPointerException: 'format' cannot be null when 'data' isn't null.
{noformat}
This was checked by building a CloudEvent this way for a String, JSON text,
byte[], Map, POJO, number, stream and file body: all fail. The call has been
there since the component was added (CAMEL-20552). The only test of the module,
EventGridComponentTest, configures endpoints and never sends, so it was not
seen.
While fixing it, note what BinaryData.fromObject does with the body, as the
data is the JSON serialization of the object: a Map or a POJO becomes a JSON
object (what Event Grid expects), but text becomes a JSON string (JSON text is
sent quoted, not parsed), bytes a base64 string, an InputStream an empty object
and a File its path. The fix could pick CloudEventDataFormat.JSON for a Map or
a POJO, send text that is JSON and bytes as they are (BinaryData.fromString /
fromBytes), and read a stream or a file, plus a test that sends with a mocked
publisher client.
Found while declaring the catalog body types of the component:
