spot_monitor trowing errors at record pace

[TheToddLuci0]

Every invocation of the spot_monitor lambda throws the following errors:

Getting the matching email every minute is not my favorite thing.

Update

Issue appears to have been caused by a campaign that ended (keyspace exhausted), but wasn't properly cleaned up. Canceling the campaign via the ui has (for the moment) stopped the errors, and given my inbox some peace. Not sure what cosmic bit-flip resulted in that campaign not being properly closed down.

This issue has raised it's head again. Running latest version, seems to be the same issue, though this time the erroneous job failed due to timeout rather than keyspace exhaustion.
