BaseDocumenter only works with HSQLDB databases.
biblio.odb is a Dbase file.
Have looked at the documentation and it states:
Limitations of the current release of BaseDocumenter
BaseDocumenter is a quite complex software. Obviously most tests have been done with HSQLDB (both 1.8 and 2.x versions) as targeted database.
Some tests have been done with MSAccess (2003 and 2007 formats), SqLite and Postgres. With success.
The availability of the 3.0 version being very recent, at this moment of time the software does not accept Firebird as back-end.
This would also exclude Dbase.
Had tried this when it first was released. Was not into dealing with something I was not going to use. At the time it was HSQLDB only. Got it to work but not happy with output. Seemed to need a lot to get something usable in Linux.
Because of this question and the note of PostgreSQL working, decided to try again.
Using Ubuntu 20.04 with LO v220.127.116.11 I installed the latest BaseDocumenter extension. When trying to create a repository it had a syntax error. Tried the other two versions (including the original I had working) and they each had errors.
May take another look some other time but this has been a disappointing effort at least in my trials.
Same error on latest two versions:
And error on oldest:
