The SubscriptionId field is required

[timvdh]

For some reason the appservice-acmebot bot stopped working and the function overview states: "Failed to load functions" (I am not aware that I changed anything). I thought this is a good time to upgrade from v3 to v4, so I changed

FUNCTIONS_EXTENSION_VERSION=~4
WEBSITE_RUN_FROM_PACKAGE=https://stacmebotprod.blob.core.windows.net/appservice-acmebot/v4/latest.zip

in env. The func still can't load, but now overview also states:

Microsoft.Extensions.Options: DataAnnotation validation failed for 'AcmebotOptions' members: 'SubscriptionId' with the error: 'The SubscriptionId field is required.'.

I tried adding Acmebot:SubscriptionId in env (Acmebot:AzureDns:SubscriptionId already existed) but same result.

That error occurs when Acmebot:SubscriptionId is not set correctly, so please make sure it is saved again. Then, if necessary, restart the system to see if the error has been resolved.

Yes, functions worked again the other day, I didn't even have to do anything.
