Upgrading Tableau to 2023.1.2 (Invalid regular expression "allowed_from_address"

[pgibbs2]

I've used vizalerts for over a year now working flawlessly. After upgrading to 2023.1.2 I'm now receiving the following error:

MainThread - 2023-06-26 14:02:05 - [DEBUG] - send_email - email body: Could not process source viz data from VizAlertsConfig/ScheduledTriggerViews for the following reason:

Invalid regular expression found. Could not evaluate expression '' in the field allowed_from_address. Raw error:

allowed_from_address

tried changing allowed_from_address to ".*" and also the data.coldelimiter, but neither of those helped so I set them back to where they were.

Thanks for logging, @pgibbs2. This is an issue that affects VizAlerts but seems to be an issue with on the Tableau Server side. More details, and a potential fix, can be found here. Can you let us know if reconfiguring the gateway.public.host config value, then applying changes with a restart resolves it?

Created #209 to improve error messaging when this happens.
