hi, I'm trying to profile a table in an Oracle database. This table has numeric, date, and varchar fields. I'm just enabling the profiling without any additional configuration. During the profiling run, I get some warnings at the start of the run of the type:

[2022-06-08 16:19:17,123] WARNING  {great_expectations.dataset.sqlalchemy_dataset:1814} - No recognized sqlalchemy types in type_list for current dialect.

Later, I get the following non-fatal exceptions (there are many of them; I'm assumin one for each 'problematic' field):

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/marco/tmp/datahub/.env/lib/python3.9/site-packages/datahub/utilities/sqlalchemy_query_combiner.py", line 246, in _sa_execute_fake

AttributeError: 'str' object has no attribute 'inner_columns'

Eventually the profiling ends and the Stats tab on the UI is populated partially. All the numeric fields have these stats set as null: min, max, mean, median, std dev Any idea on what's the issue here?

hey @ambitious-rose-93174 did you find the solution to this?
