Azure time triggered function fails to deploy with ServiceUnavailable

Question

Hi,

I have a fairly simple Azure Function that is triggered on a cron schedule, and has been working fine for months.

A few days ago I made a few simple changes and tested locally that it was working, then did a deploy through the VS code plugin.

Most of the stages went through fine e.g. the pip package install including a 'deployment successful' message. However it then failed 'syncing triggers':

13:53:35 Grafham-flag: Deployment successful.
13:53:47 Grafham-flag: Syncing triggers...
13:53:52 Grafham-flag: Syncing triggers (Attempt 2/6)...
13:54:03 Grafham-flag: Syncing triggers (Attempt 3/6)...
13:54:23 Grafham-flag: Syncing triggers (Attempt 4/6)...
13:55:04 Grafham-flag: Syncing triggers (Attempt 5/6)...
13:56:24 Grafham-flag: Syncing triggers (Attempt 6/6)...
13:56:25: Error: Encountered an error (ServiceUnavailable) from host runtime.

I did change the schedule, but only trivially, extending the hour range, and the error sounds like something is down on the azure side - but I've tried this a few times now yesterday with the same result.

Thanks,
Jon

This appears to be known issue with VS extension, re: unable to deploy python app from VS code extension - ServiceUnavailable
