'aws directory service directory' creation timeouts

I’m having a pretty hard time getting the aws_directory_service_directory resource to build consistently. I’ve been successful one time and about a dozen other times it simply times out. Looks like the max time is around 30 minutes. I’m fairly new with terraform so apologies if this is a known issue or has a workaround. I dont see any timeout parameters, so is this just a hit or miss type of resource? Same results in whether its useast1/2 or uswest1/2
