Hi Experts,  
I’m trying to configure and integrate SCIM 2.0 connector and during integration, I’m trying to preview the attribute and face below issue.  
Does anyone face same issue in IIQ 8.4 Version during SCIM 2.0 connector integration.

Error :  
class java.lang.String cannot be cast to class java.lang.Boolean (java.lang.String and java.lang.Boolean are in module java.base of loader ‘bootstrap’)

hello @Mandar45 this error might be caused by changing the ‘active’ attribute from a string to a boolean, Can you check by changing the ‘active’ schema type to String and then test the connection?

@santhirajumunganda, I’ve made the changes and the test connection was established successfully. However, I’m still facing the same error.

hi few thinks to check before you do the aggregation. Did you get the schema attributes when you do discover schema or did you add them manually. Usually you have to do a discover schema and the schema attributes should populate using discovery endpoints. Once it is done just validate if the type of the attribute is matching with your endpoints get account response. Validate your response in postman and see the type of your account attributes.

Please check all schema attributes that are configured as Boolean type. Try changing them to String.

Also, check if there are any customization rules in place — it’s possible that a data type is being explicitly cast there.

Please add tracing for the `ResourceObject` within your customization rule to identify which schema attribute contains the Boolean value.

Hello @Mandar45

Check response from postman and accordingly set schema attributes in sailpoint application configuration

- If SCIM returns a **boolean** , set `type = boolean`.
- If SCIM returns a **string** `"true"` / `"false"` instead, **change it to `string` in the schema** to avoid casting errors.

Based on the response you have subattributes for groups, roles etc., looks like they are additional attributes and the endpoints is designed to give you additional info. You need to get only the required info like groups.value. The type for groups will be group (entitlement object) which you would have created. I see for roles you have mapped with role so similarly for groups it should be group.
