db_url() fail with oracle dsn

[lsaavedr]

db_url fail with oracle url without path, for example:

import environ
env = environ.Env()

DB_URL = 'oracle://super_user:super_pass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=oracle_dev)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XEPDB1)))'

DB = env.db('', default=DB_URL)
print("NAME:", DB['NAME'])

NAME: %28DESCRIPTION=%28ADDRESS=%28PROTOCOL=TCP%29%28HOST=oracle_dev%29%28PORT=1521%29%29%28CONNECT_DATA=%28SERVICE_NAME=XEPDB1%29%29%29

but with path (adding a simple / to de end): DB_URL = 'oracle://super_user:super_pass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=oracle_dev)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XEPDB1)))/':

NAME: (description=(address=(protocol=tcp)(host=oracle_dev)(port=1521))(connect_data=(service_name=xepdb1)))
