Planning to Migrate from BTS2013R2 to BTS2020. HIS DB2 adapter is essential in our landscape for still a while.

When re-cerating a SendPort to DB2 in BTS2020 / HIS2020 the SendPort thrown an error. The connection string is created using the Data Access Tool. Test connecting in thistool is successful.
Visual Studio 2019 generated the Stored Procedure schema by using the 'Add Adapter Metadata' option.

Is there any solution for the error thrown by the sendport:

System.Exception: There was an error in the Send port with URI: <correct uri>.
Internal message: There was an error in the Send port with URI: <correct uri>.
Internal message: Object reference not set to an instance of an object.

    Make sure to Download Host Integration Server 2020 Cumulative Update 1 from Official Microsoft Download Center install that and reboot.

    If that still doesn't fix the issue, raise an issue with Microsoft, and ask them for HIS2020-Server-BTSAdapters-KB5046904-x64-EN

    This caused the Receive Locations to start having the same issue, changing the Host CCSID to 1208 in the connection string resolved this.
