--------------------------------------
Summary: Kamelet jslt-action not handling byte[] input
Key: CAMEL-18368
URL: https://issues.apache.org/jira/browse/CAMEL-18368
Project: Camel
Issue Type: Improvement
Components: camel-k
Environment: The samples have been tested with the Camel K Operator
1.9.x on an OpenShift environment.
Reporter: Bruno Meseguer
Attachments: stage1-telegram-jira.tar.gz
the [jslt-action] kamelet, based on the JSLT component is very handy for
performing data transformations with JSON input.
However, when configuring KameletBindings, for non-Camel users, it becomes
tricky as some Kamelet sources deliver JSON in byte[]. If we bind for example a
Telegram Source with the JSLT action before sending it to some backend, the
process fails with the following message:
{code:java}
org.apache.camel.ValidationException: Allowed body types are String or
InputStream.. Exchange[]{code}
One way to work around the problem is to customise the JSLT-action to convert
the body to String, or modify the Telegram source to deliver String JSON
payloads.
Attached is a sample project containing a modified JSLT-action and a sample
KameletBinding connecting Telegram to the JSLT action. Note the modified action
converts the body to String.
