Management VRF and copy config file (TFTP)

I have setup a VRF for management.
But I cannot figure out a way to use it to copy config files to/from tftp.
I can specify the VRF for things like ping, but he copy command does not seem to support this.
Are there any options for this, or does this need to be a feature request?

I figured it out.
The problem was not with the vrf and routing table.
The problem seems to be with the copy command.

vyos@R1:~$ copy file /config/ to tftp://
curl: (3) URL using bad/illegal format or missing URL

I used curl directly and it worked just fine.
curl -T /config/ tftp://

Interesting thing is that is only available in the management VRF, does not show up in the routing table, and other tools like ping cannot find their way to this subnet.

Anyway, there may be a bug with the copy command. Or I am not using the command correctly.
I am running VyOS 1.3-rolling-202010012001
