Unable to clone with message "Instance is pending a clone source request and cannot be overwritten. You must cancel or wait for existing clone requests to complete before submitting any new requests."Issue Since London, administrators can schedule multiple clones, with the instance performing a check if any previous clone schedule is still pending in the datacenter. If a previous clone got stuck, it will be impossible to schedule a new request, and an error message is shown:"instance <instance_name> is pending a clone source request and cannot be overwritten. You must cancel or wait for existing clone requests to complete before submitting any new requests." CauseThe most likely scenario for this error is described here: You want to clone instance A (Prod) over instance B (Test)A clone record already exists in 'requested state' to clone instance B (Test) over instance C (Dev). So the fact that instance B is scheduled as the clone source for a future clone, prevents it from being cloned over.ResolutionCancel the existing pending clone record or wait for the existing clone to complete.
