Database restore feature is BROKEN - currently awaiting support

As a follow-up, this has been escalated - regardless of using the web or cli I am getting this error.

An error occurred (InvalidInputException) when calling the CreateRelationalDatabaseFromSnapshot operation: The sourceRelationalDatabaseName must be specified together with restoreTime or useLatestRestorableTime.

(All parameters double-checked)

At this moment it appears that point in time recovery is broken entirely unless the API is throwing the wrong error when the disk is full??? Seems very unlikely...

Thanks for reporting the issue. We are looking into the issue and will work toward a fix as soon as possible.

Thanks,
Steve

Just wanted to say thanks to AWS Support, once we were on the Business plan and I could demonstrate over a web chat that it was definitely nothing on my end that was wrong they very quickly amended my Lightsail RDS instance so that it could accept connections again.

The fix for the issue you mentioned was released. It's great to hear that your issue is resolved. Thanks for reporting the issue to us.
