Start with the linked Sentry report and the SQLAlchemy execution path named in the traceback, especially sqlalchemy/engine/base.py and sqlalchemy/engine/default.py. Determine which input contains the NUL character and where it enters the statement or parameters; done should include a confirmed cause and a regression test or clearly documented resolution.
