Error message for POST Node but status code is 202

Hi,

I am doing an POST API call to MYOSH, Viking API endpoint, the result status I am getting back is 202, but there is still an error message: The entity is not backed by an input stream, entity class is : java.io.InputStream
Has anyone seen this before. I am not sure if this is an issue at the Endpoint or KNIME. If I know which side the issue is I can then focus on trying to find the reason for an 202 result to produce an error message as well.

Regards
Willem.
