WSO2 Micro Integrator: How to handle "application/json; odata.metadata=minimal" content-type from backend?

I'm trying to handle responses with content-type "application/json; odata.metadata=minimal" from a backend service in WSO2 Micro Integrator but facing issues.

[2024-10-29 11:05:53,099] ERROR {JsonStreamBuilder} - Error occurred while processing document for application/json java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)   at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566)

What I've already tried:

I've added the following configurations to deployment.toml:

[[custom_message_builders]]
content_type = "application/json; odata.metadata=minimal"
class = "org.wso2.micro.integrator.core.json.JsonStreamBuilder"

[[custom_message_formatters]]
content_type = "application/json; odata.metadata=minimal"
class = "org.wso2.micro.integrator.core.json.JsonStreamBuilder"

but still the same issue.

Solution

  • It seems the backend sends data which is encoded using Brotli compression. Let's try to remove the accept-encoding header and see whether we can resolve the issue. Before calling the backend, let's add below property.

      <header action="remove" name="Accept-Encoding" scope="transport"/>
