Oracle 23 throws ORA-26701: XStream process does not exist

Question

I am presently evaluating Oracle 23's FREE image with XStream using the Oracle Container Registry image having completed the following custom-setup options:

• Created the recovery_area path in the image for archive logs.
• Set db_recovery_file_dest_size and db_recovery_file_dest and enable_goldengate_replication.
• Enabled archive log mode and bounced the database after above configurations.
• Created the c##xsadmin tablespaces in both the FREE and FREEPDB databases.
• Created the user c##xsadmin in the FREE root database assigned to its tablespaces.
• Grant CREATE_SESSION, SET CONTAINER, XSTREAM_CAPTURE, and XSTREAM_APPLY to the c##xsadmin user.
• Created a local user in FREEPDB1 that I connect with the following grants: CONNECT, CREATE SESSION, CREATE TABLE, CREATE SEQUENCE.
• Created the c##xsuser tablespaces in both the FREE and FREEPDB1 databases.
• Created the common user c##xsuser in the FREE root database specifying the c##xsuser tablespaces above.
• Grant CREATE SESSION, SET CONTAINER, SELECT ON V$DATABASE, FLASHBACK, SELECT_CATALOG_ROLE, and EXECUTE_CATALOG_ROLE to the c##xsuser common user.

With those steps in place, I begin to create the XStream outbound server by running the following using the c##xsadmin user in the FREE database:

DECLARE
  tables  DBMS_UTILITY.UNCL_ARRAY;
  schemas DBMS_UTILITY.UNCL_ARRAY;
BEGIN
    tables(1)  := NULL;
    schemas(1) := 'debezium';
  DBMS_XSTREAM_ADM.CREATE_OUTBOUND(
    server_name     =>  'dbzxout',
    table_names     =>  tables,
    schema_names    =>  schemas);
END;

Finally, I reconnect as the sys user with sysdba role and execute:

DBMS_XSTREAM_ADM.ALTER_OUTBOUND(
  server_name  => 'dbzxout',
  connect_user => 'c##xsuser');
END;

In the container I see XStream and GG start:

Running SELECT dbms_apply_process.get_apply#('DBZXOUT'); outputs:

Running SELECT STATE FROM V$PROPAGATION_RECEIVER; outputs:

DBXOUT | C##XSUSER | CAP$_DBXOUT_1 | FREE | C##XSADMIN | C##XSADMIN

I have also checked DBA_ALERT_HISTORY and DBA_OUTSTANDING_ALERTS for good measure and I don't get any results, so I'm really baffled as to why when my client attempts to attach to the XStream process, I get the error:

Caused by: oracle.streams.StreamsException: ORA-26701: XStream process DBZXOUT does not exist

I compared this to my steps for Oracle 19 and the only difference I found was needing to assign XSTREAM_CAPTURE and XSTREAM_APPLY roles rather than using the DBMS_XSTREAM_AUTH.GRANT_ADMIN_PRIVILEGE package and it works for that version.

Does anyone have any suggestions on what I may have done incorrectly?
