I am using BITES in a Python application and have created a database as follows:

```auto
admin = stardog.Admin(**sd_conn_details)
admin.new_database(database,
                      {'search.enabled': True, 'edge.properties': True, 'reasoning': True,
                       'reasoning.punning.enabled': True, 'query.timeout': '20m',
                       'docs.default.rdf.extractors': 'tika, text'})

```

According to the docs, 'text' is a built-in extractor.

I add a document to the BITES store using this code:

```auto
conn = stardog.Connection(database, **sd_conn_details)
docs = conn.docs()
conn.begin()
docs.add(doc_name, stardog.content.Raw(doc_text))
conn.commit()

```

Without the database option, docs.default.rdf.extractors, everything works as expected. With the option, I get an exception:

```auto

Try removing the space between `tika, text` -\> `tika,text`.
