Cannot read external table or read using utl_file.get_line on Windows 10 with Oracle 18c

Question

I just upgraded to Oracle 18c XE from 11g. I have an external table that worked fine on 11g, but I keep getting the following errors on 18c.

ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-11604: no directory object specified for log file

The directory does exist and I have the correct grants.

SELECT *
FROM   all_directories
WHERE  directory_name = 'MYDIR';

OWNER  DIRECTORY_NAME  DIRECTORY_PATH  ORIGIN_CON_ID
SYS  MYDIR  C:\Users\sneuf\OneDrive\PLSQL\OracleDirectory  1

I have the required privileges.

SELECT * 
FROM all_tab_privs 
WHERE table_name = 'MYDIR' 
AND grantee = 'C##_SNEUF'; 
GRANTOR GRANTEE TABLE_SCHEMA TABLE_NAME PRIVILEGE GRANTABLE HIERARCHY COMMON TYPE INHERITED 
SYS     C##_SNEUF    SYS         MYDIR    EXECUTE      YES     NO       NO   DIRECTORY NO 
SYS     C##_SNEUF    SYS         MYDIR    READ         YES     NO       NO   DIRECTORY NO 
SYS     C##_SNEUF    SYS         MYDIR    WRITE        YES     NO       NO   DIRECTORY NO

I'm pretty sure I'm missing a grant somewhere, but I can't figure out what. Can someone please help?

Here is my table:

CREATE TABLE C##_SNEUF.CHECKING_TBL_EXT2 
   (  
  DB_KEY NUMBER, 
  CHECK_NUM VARCHAR2(10), 
  TRANS_DATE TIMESTAMP (6), 
  DESCRIPTION VARCHAR2(100), 
  DEPOSIT_WITHDRAWAL VARCHAR2(1), 
  AMOUNT VARCHAR2(12), 
  MEMO VARCHAR2(200)
   ) 
   ORGANIZATION EXTERNAL 
    ( TYPE ORACLE_LOADER
      DEFAULT DIRECTORY MYDIR
      ACCESS PARAMETERS
      ( RECORDS DELIMITED BY NEWLINE
    BADFILE MYDIR: 'checking.bad'
    FIELDS TERMINATED BY ","
    OPTIONALLY ENCLOSED BY '"'
    LDRTRIM
    MISSING FIELD VALUES ARE NULL
(
  DB_key CHAR,
  check_num CHAR(10),
  trans_date CHAR(21) DATE_FORMAT DATE MASK 'MM/DD/YYYY HH24:MI:SS',
  description CHAR(100),
  deposit_withdrawal CHAR(1),
  amount CHAR(12),
  memo CHAR(200)
            )
                     )
      LOCATION
       ( MYDIR: 'checking.csv'
       )
    )
   REJECT LIMIT UNLIMITED ;

Thanks, Steve

Logfile isn't specified, so - by default - it resides in the same directory as the data file.

However, as you write to log file, you require write privilege on the MYDIR directory. Info you posted suggests that you have only READ privilege so - grant WRITE as well.
