OIC- Map empty json sub-node set to csv

Hi,

I have the requirement to map input json data to csv output.

In the input data we have Courses and for each course, we have a liste of existing sessions planned for that course.

For each course there con have zero or many session planned.

Everything works fine when there is one or more session planned for a course. But when there is no session availlable, I'm getting error message:

"

Exception while processing Invoke request for endpoint <WriteFile_REQUEST>. Error Message : Translation Error.

Translation Error.

Error while translating message to native format.

Please make sure that the payload for the outbound interaction conforms to the schema and payload size does not exceed threshold. Error occured as {1}
