You described, may be, different bug or depended. I'll try again to explain.

First error was:

"invalid value for parameter
""basic_archive.archive_directory"": ""/mnt/ocean/postgres/stars/
WAL""","Specified archive directory does not exist."

And this is, may be, correct. But second, just after the first:
"""archive_mode"" enabled, yet archiving is not
configured","basic_archive.archive_directory is not
set."

The value of basic_archive.archive_directory
was erased after the first error. But it was erased only inside archive_library 'basic_archive', postgresql itself it was still
basic_archive.archive_directory=/mnt/ocean/postgres/stars/
