I think the problem is I yesterday entered extended bolus and then cancelled it, so bolex_completion_time='', bolex_start_time=''. Here's what I see in the debugger:

Thanks for the detailed report!

By any chance could you provide the raw data from tconnect so I can write a test case to cover this? That would be the variable b inside the loop through bolusdata in process_bolus_events in the same context as the print(event) you provided.

I released v0.8.9 with a prototype fix.
