Cannot deserialize HTTP error response: JsonbException: Cannot create instance of a class: class com.unboundid.scim2.common.messages.ErrorResponse, No default constructor found.

Description Error responses from SCIM provider cannot be deserialized. Error:

To Reproduce I see this across a variety of 4xx responses from different SCIM providers.

Additional context

• Spring Boot version: 3.2.5
• Java version: 17, 21
  • SCIM 2 SDK version: 3.0.0

Hi @wedgec, could you provide some reproduction steps for this issue? It's not clear to me how to recreate this behavior.

From a first glance, I noticed that you're using the JSON-B parser to deserialize the data. The SCIM SDK leverages the Jackson library for serialization and deserialization. Is it possible to update your Spring configuration to use Jackson instead of JSON-B?

[wedgec]

That helps, I'll look into that!

I found the problem and a fix.

I was using bearer token auth, following the directions in the wiki. The problem is that the jersey-media-json-binding library is a transitive dependency of org.glassfish.jersey.security:oauth2-client, required for OAuth. I excluded the JSON-B library in my gradle build script as follow, and voila!

implementation 'com.unboundid.product.scim2:scim2-sdk-client:3.+'``
implementation ('org.glassfish.jersey.security:oauth2-client:3.+') {
    // Disable JSON-B in SCIM client (in favor of Jackson)
    exclude group: 'org.glassfish.jersey.media', module: 'jersey-media-json-binding'
}

Perhaps you can add this workaround to the wiki?

Thanks for reporting that back. I agree it'd be good to add that to the wiki. I'm also in the process of adding an FAQ section, and I think it would be a good addition there too.

I've updated the wiki to clarify this. Thanks again for reporting this issue.
