this looks like something up with the environment or the interpreter. The error
message says it got an object whose type() returns "BinaryExpression". that is
exactly the type it is looking for; this class should be a subclass of
sqlalchemy.sql.visitors.Visitable. However for this error to occur, that is
suddenly not the case, or the Visitable / BinaryExpression symbol has been
modified at runtime, something like that. It's not clear if this could be some
artifact of AWS Lambda, or the way the application is doing imports, or
something like that.
the approach here would be to make a test program that produces the error under
AWS Lambda, then run it in a local Python environment and see if the results
are the same or different.
