Can't create more than one route to route table

[kunalvudathu]

This is the snippet of the code I used:

mock_rtb_private_1_id = ec2.create_route_table(VpcId=mock_vpc_id)['RouteTable']['RouteTableId']
ec2.create_route(DestinationCidrBlock="10.0.0.8/8", NatGatewayId=mock_igw_id,
                     RouteTableId=mock_rtb_private_1_id)
ec2.create_route(DestinationCidrBlock="0.0.0.0/0", NatGatewayId=mock_nat_1['NatGatewayId'],
                     RouteTableId=mock_rtb_private_1_id)

I get the following error when I try to create the second route (line 3):

botocore.exceptions.ClientError: An error occurred (RouteAlreadyExists) when calling the CreateRoute operation: The route identified by 0.0.0.0/0 already exists

Thank you so much!

Hi @kunalvudathu, which version of Moto are you using? Because this looks very similar to #6096 (fixed as of moto >= 4.1.6.dev17)

I was using 4.1.3, it works now! Thank you! Sorry about that.
