Data pump import to ATP failing with ORA-17500: ODM err:ODM HTTP Unauthorized

Hello,

I'm trying to import data from on premise database 12.2.0.1 to ATP database 18 Free tier

expdp and impdp are version 12.2.0.1

export file named DEMOSOT12.DMP is uploaded to Oracle Cloud infrastructure Object Storage

Firstly I created Auth Token

Then I created credential:

begin

DBMS_CLOUD.CREATE_CREDENTIAL(

credential_name=> 'DEF_CRED_NAME',

username => '<my_username>',

password => '<MY_TOKEN>'

);

end;

/

dbms_cloud.enable_credential(credential_name => 'DEF_CRED_NAME');

alter database property set default_credential='ADMIN.DEF_CRED_NAME';

and then I tried import using native URI format

impdp admin/pass@database directory=data_pump_dir  dumpfile=DEF_CRED_NAME:
