Intermittent TypeError in get_sql_value: isinstance() arg 2 must be a type, a tuple of types, or a union about piccolo

[dantownsend]

Interesting - I had a look at the code for get_sql_value and I can't see any obvious issues.

piccolo/piccolo/columns/base.py

Line 868 in d1f6c35

elif isinstance(value, datetime.datetime):

Which Python version are you running?

I Googled around, and found this discussion, but it's pretty old.

I wonder if there's anything in Piccolo or your application code which does something like:

datetime.datetime = 'foo'

i.e. overrides datetime.datetime, which then causes isinstance to fail.
