Fails to add static route on VPC #12782

problem

There is a static route option in the VPC itself in addition to the one present on the private gateway.

It expects a next hop. When adding the static route with the destination network CIDR and an existing private gateway, it fails.

The static route can be added directly on the private gateway.

versions

4.22.0

The steps to reproduce the bug

1. Create a VPC
2. Create a private gateway
3. Go back to VPC and click on the static routes
4. Add a static route and next hop ( use the above private gateway , gateway IP)
5. It fails to add
   ...

What to do about it?

It needs to be fixed.
