initially i had created tblspace outside pg_data env variable

e.g PG_DATA env variable is defined to /XXX/YYYY/ABC/15/data

the tablespace was created under /XXX/YYYY/ABC/15/tblspace/<<tbl_spcname>>/

assume tablespace name is abc_data

cd /XXX/YYYY/ABC/15/tblspace/abc_data/

ls -atl

drwxr-x---. 2 postgres postgres 6 Dec 19 22:08 PG_15_202209061

ls -altR

drwxr-x---. 2 postgres postgres 6 Dec 19 22:08 PG_15_202209061

i reconfirmed

SELECT * FROM pg_tablespace ;

oid | spcname | spcowner | spcacl | spcoptions

------+------------+----------+--------+------------

1663 | pg_default | 10 | |

1664 | pg_global | 10 | |

not having any entry about tablespace abc_data

Can you guide

From:

https://www.postgresql.org/docs/current/manage-ag-tablespaces.html

"The directory $PGDATA/pg_tblspc contains symbolic links that point to
each of the non-built-in tablespaces defined in the cluster."

Is there a symlink at the above location?

Does the directory in the image have files?
