router_field_not_supported

HTTP 422 A router image takes only a public address and one private network - the platform sets the name, the size and the credentials itself

What happened

A create request using a router image carried a field the platform sets itself: name, cores, memory_mb, disk_gb, plan_id, password, ssh_keys, setup or accept_license. Only a field with real content is refused - an empty list, an empty object, false and an empty string are ignored, so a generated client may send the full schema.

What to do

Remove the field that carries a value and keep only public_ipv4 and exactly one entry in networks. A router's size, name and credentials come from the platform and cannot be changed later either, so nothing is lost by omitting them.

Retrying

Fix the request and send it again.
