Unknown system variable 'transaction_isolation'

Hi,

I am currently getting the following exception when using .sms on a MariaDB database:

File "/Users/<user_name>/Documents/Projects/isb/knowledge-graph/.venv/lib/python3.9/site-packages/stardog/admin.py", line 565, in new_datasource
    self.client.post("/admin/data_sources", json=meta)
  File "/Users/<user_name>/Documents/Projects/isb/knowledge-graph/.venv/lib/python3.9/site-packages/stardog/http/client.py", line 50, in post
    return self.__wrap(self.session.post(self.url + path, **kwargs))
  File "/Users/<user_name>/Documents/Projects/isb/knowledge-graph/.venv/lib/python3.9/site-packages/stardog/http/client.py", line 72, in __wrap
    raise exceptions.StardogException(
stardog.exceptions.StardogException: [500] 000012: Unknown system variable 'transaction_isolation'

Within MariaDB the variable name for this is tx_isolation. I am unsure how to resolve the issue? Any help is appreciated.
