ORA-00001: unique constraint (BITBUCKET.SYS_PK_10133) violated

Hi

my Bitbucket Troubleshooting is showing:
Bitbucket Server throwing ORA-00001: unique constraint violated

In the logs it shows:
2020-12-26 15:45:05,346 ERROR [Caesium-1-2] o.h.e.j.batch.internal.BatchingBatch HHH000315: Exception executing batch [java.sql.BatchUpdateException: ORA-00001: unique constraint (BITBUCKET.SYS_PK_10133) violated
], SQL: insert into cwd_directory_attribute (directory_id, attribute_name, attribute_value) values (?, ?, ?)
2020-12-26 15:45:05,346 WARN [Caesium-1-2] o.h.e.jdbc.spi.SqlExceptionHelper SQL Error: 1, SQLState: 23000
2020-12-26 15:45:05,346 ERROR [Caesium-1-2] o.h.e.jdbc.spi.SqlExceptionHelper ORA-00001: unique constraint (BITBUCKET.SYS_PK_10133) violated

I have tried to follow these instructions:
https://confluence.atlassian.com/bitbucketserverkb/bitbucket-server-throwing-ora-00001-unique-constraint-violated-938840755.html?utm_medium=logScan&utm_source=STP
But the first statement points to CWD_DIRECTORY_ATTRIBUTE.
And this isn't shown in the second statement.

Does somebody know how to fix this?

Thank you very much in advance

Christoph
