   Thanks @tvalentyn. I repro'ed and got the full stack trace"
   
   ```
         Root cause: Python exception: Traceback (most recent call last):
     File "apache_beam/runners/common.py", line 1417, in apache_beam.runners.common.DoFnRunner.process
       return self.do_fn_invoker.invoke_process(windowed_value)
     File "apache_beam/runners/common.py", line 623, in apache_beam.runners.common.SimpleInvoker.invoke_process

       results = results or []
   ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
   ```
   
   This looks to be due to an unnecessary cleanup I included in 0de98210f4531fbfd88265bc02052b27bd299602: https://github.com/apache/beam/commit/0de98210f4531fbfd88265bc02052b27bd299602#diff-350e908b1c77bb2c78ff5a16f77e7da591ea87dd3911a296be8c598162896b19R1608
   
   I will roll that part back and propose a cherrypick.
