Validating User Api Access from Database

[cdeveloper10]

Description

I recently integrate Wso2 APIM With Identity Server 4 and Want To Access To Backend API with Identity server 4 as Token manager
the full configuration is done but when wso2 wants to check user's API access runs this Query in Database :

exec sp_executesql N'SELECT AM_APPLICATION.UUID, AM_APPLICATION_KEY_MAPPING.APPLICATION_ID,AM_APPLICATION_KEY_MAPPING.CONSUMER_KEY,AM_APPLICATION_KEY_MAPPING.KEY_TYPE,AM_KEY_MANAGER.NAME AS KEY_MANAGER,AM_APPLICATION_KEY_MAPPING.STATE FROM AM_APPLICATION_KEY_MAPPING,AM_KEY_MANAGER,AM_APPLICATION WHERE AM_KEY_MANAGER.UUID = AM_APPLICATION_KEY_MAPPING.KEY_MANAGER AND AM_APPLICATION_KEY_MAPPING.APPLICATION_ID = AM_APPLICATION.APPLICATION_ID AND AM_APPLICATION_KEY_MAPPING.CONSUMER_KEY = @p0 AND AM_KEY_MANAGER.NAME = @p1 AND AM_KEY_MANAGER.ORGANIZATION IN ( @p2 , @p3 )',N'@p0 varchar(8000),@p1 varchar(8000),@p2 varchar(8000),@p3 varchar(8000)','null','IS4_2','carbon.super','WSO2/System'

as you can see there is 'null' value as parameter @p0 assigned to AM_APPLICATION_KEY_MAPPING.CONSUMER_KEY

i want to know why this parameter has 'null' value because the Client_id in the claim exists and there is also the Client_id in the Identity server Introspect service

Steps to Reproduce

1 - Generate Client in the Dev portal for Identity server 4
2 - Generate Access token with first step Credential
3- Call Wso2 APIM Services that users Subscribed to

Could you please verify the API Manager and IS product versions that you are trying out?

[cdeveloper10]

Wso2 apim 4.3.0

You have mentioned that you use an Identity Server as well, What would be the version of that. I believe it's a WSO2 Identity Product.

Thank for your Response
The Problem Is Solved
I Noticed That Each Key Manager Type That Define in Wso2 Admin Console Has Its Own Subscription Validation Model.

At First I Used KeyClock as Key Manager Type And Then I Tried Wso2 Identity Server 7 To Link With Identity Server 4 And Now Everything Works Just Fine with Wso2 Identity Server 7 as Key Manager Type.
