I have a DataService (behind a managed API) that have to receive a JSON gziped (as it is a large dataset).
Micro integrator: WSO2MI-4.2.0 API Manager : WSO2AM-4.2.0 Identity MGT: WSO2IS-6.0.0
But I receive this error message:
<faultstring>I/O Exception occured while building the data service request</faultstring>

Try adding the following to the deploymet.toml
[[custom_message_builders]]
class = "org.wso2.carbon.relay.BinaryRelayBuilder"
content_type = "application/gzip"
[[custom_message_formatters]]
class = "org.wso2.carbon.relay.ExpandingMessageFormatter"
content_type = "application/gzip"
