Claus Ibsen created CAMEL-25987:
-----------------------------------
Summary: camel-jsonata - with the default inputType a JSON text
body is read as one JSON string, and the expression gives an empty result
Key: CAMEL-25987
URL: https://issues.apache.org/jira/browse/CAMEL-25987
Project: Camel
Issue Type: Bug
Affects Versions: 4.18.0, 4.22.0, 4.23.0
Reporter: Claus Ibsen
Fix For: 4.24.0
With the default {{inputType}}, {{Jackson}}, the jsonata producer converts the
body with {{mapper.convertValue(body, Object.class)}} ({{JsonataEndpoint}},
main e6885df7894d, line 152). Only {{inputType=JsonString}} parses JSON text
(line 148). A JSON text body therefore becomes one JSON string, and a path
expression on it finds nothing: the result is an empty object or null, with no
error. A byte[] is refused by JSONata ("Only JSON types (values, Map, List) are
allowed as input"), and a stream fails in {{convertValue}}.
Checked on 4.24.0-SNAPSHOT with {{camel run}} and the expression
{{\{"fullName": name\}}}:
* the body {{\{"name": "Camel"\}}} as text, with the default options, gives an
empty ObjectNode;
* the same text with {{inputType=JsonString&outputType=JsonString}} gives
{{\{"fullName":"Camel"\}}};
* the same JSON as a Map, with the default options, gives an ObjectNode with
fullName.
The examples of the component docs sent a JMS text message to the default
options; they now set inputType and outputType to JsonString (CAMEL-24961).
*Proposed change*: with {{Jackson}}, parse a body that is text, bytes, a stream
or a file, as {{JsonString}} does, and convert other objects as now.
