Getting ORA-29400: data cartridge error while accessing error log

Content

I am trying to access the error log file on a shared Autonomous database infrastructure , and getting data cartridge error.

 

Following are the steps I have performed:

1) I am trying to load some data through external table

BEGIN
  DBMS_CLOUD.CREATE_EXTERNAL_TABLE (
    table_name => 'XX',
    credential_name => 'OBJ_STORE_CRED',
    file_uri_list => '<Path of CSV>',
    column_list => 'XX varchar2(50), XX VARCHAR2(10), XX VARCHAR2(10)',
    format => json_object('type' VALUE 'CSV')
  );
END;

So I get an error

Error report -
ORA-20003: Reject limit reached, query table "ADMIN"."COPY$14_LOG" for error details
