We are using the aviatrix terraform resource `"aviatrix_transit_gateway"`  to build a transit gateway but we are getting the following error. 

failed to create Aviatrix Transit Gateway:


rest API create_transit_gw Post failed:


Error: [AVXERR-MAINTENANCE-004] Upgrade/Restore in progress.


Please try again after maintenance action is finished.








with aviatrix_transit_gateway.avx_build,


 on vpc.tf line 2,


in resource "aviatrix_transit_gateway"

The following is the structure of our resource:

resource "aviatrix_transit_gateway" "avx_build" {


single_az_ha = true


gw_name = "avx_build_gw"


vpc_id = vpc.avx_build.id


cloud_type = 1


vpc_reg = var.region


connected_transit = true


gw_size = "t3.medium"


account_name = var.cloud_account_name


subnet = aws_subnet.avx_build_subnet.cidr_block


enable_advertise_transit_cidr = true


bgp_manual_spoke_advertise_cidrs = "some-ip-addr-ranges-here"


}

Is it due to an aviatrix maintenance or a possible error on our side?
