2882850 - Name is too long error using REST Adapter


You have a REST scenario (REST Sender or REST Receiver with sync-async), where REST Adapter sends a request using JSON and receives a response from the target server. After that, you execute some Operation Mapping and/or Message Mapping

While executing the Mapping, you receive the following error.

Mapping "http://<package>/xi/<scenario>/<mapping name>" failed to execute: MappingException: Mapping failed, IllegalArgumentException: Name is too long (54/50): x-ms-ratelimit-remaining-workflow-download-contentsize

The above is an example of http header that is sometimes sent by the Microsoft Dynamics System which has 54 characters and will be used as example in this document.
