Describe the bug
When we are trying to fetch Group who has some members associated with it. It throws exception.

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "type" (class com.unboundid.scim2.common.types.Member), not marked as ignorable (3 known properties: "value", "display", "$ref"])

Hi,

It seems your server is returning a 'type' field in it's response. The SCIM 2 SDK doesn't know anything about a 'type' field for the Member in the GroupResouce object. Adding a member seems to not require this 'type' field. But when you fetch the Group you get something back.

Here are a few questions that might help to solve this:
What server / service are you working with? Who is the vendor? (Every vendor / product seems to interpret the standard a bit differently)
What does the 'Schema' of your server product say about the attributes of the 'Group' -> 'Member' object? (Maybe you need to develop your own 'Group' resource class and include the 'type' attribute in your own implementation).

When I wrote a client application I checked the 'Schema' of the target server and that 'Schema' claimed to (additionally) provide a 'type' field for the 'Member' object. And there were a bunch of other issues with the provided 'Schema', which I had to workaround.

Hi,
If I develop my onw Group. Could you please let me know How i can use my Own created Group to ScimService for all group related operation?
Thanks,
Sagar

I'm not sure how your client code looks like. Therefore any advise is a bit hard.

My guess is you need to replace the usage of the 'GroupResource' with your own developed 'Group'.

Have a look at https://github.com/pingidentity/scim2/wiki/Working-with-SCIM-resources#converting-between-basescimresources-and-genericscimresources

We are running into this problem when talking to Litmos. There is a type field in the list of group members that causes Jackson to error out.

We have gotten around it by applying the code snippet in #81 in a wrapper we have around this library.

This issue should be resolved with #199, which adds the type field to the Member class. It is currently planned to be released in version 2.4.0 of the UnboundID SCIM 2 SDK.
