Important Factoids

It appears that I can work around the error by passing in an empty string to RouteTableRoute

route = _vpc.RouteTableRoute(
                cidr_block="0.0.0.0/0",
                gateway_id=igw.id,
                core_network_arn=""
            )

This is a bug that has appeared in the past with RouteTableRoute. I submitted a pull request last July when the exact same thing happened when cidr_block and carrier_gateway_id were added.

in @cdktf/provider-aws/lib/vpc/route-table.js at line 15 you can see the offending code that’s been added:

`
carrier_gateway_id: struct.carrierGatewayId === undefined ? null : cdktf.stringToTerraform(struct.carrierGatewayId),

cidr_block: struct.cidrBlock === undefined ? null : cdktf.stringToTerraform(struct.cidrBlock),

core_network_arn: cdktf.stringToTerraform(struct.coreNetworkArn),

destination_prefix_list_id: struct.destinationPrefixListId === undefined ? null : cdktf.stringToTerraform(struct.destinationPrefixListId),

egress_only_gateway_id: struct.egressOnlyGatewayId === undefined ? null : cdktf.stringToTerraform(struct.egressOnlyGatewayId), `

Notice how all the variables set null if they’re undefined other than the newly added “core_network_arn” which just doesn’t set anything if it’s undefined. That value HAS to be set null if it’s undefined
