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/config.boot.save to tftp://10.1.1.11/vyosR1
curl: (3) URL using bad/illegal format or missing URL

I used curl directly and it worked just fine.
curl -T /config/config.boot.save tftp://10.1.1.11/vyosR1

Interesting thing is that 10.1.0.0/16 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
