Error during server attributes patching: (%s) %s

Error message

Error during server attributes patching: (%s) %s

What it means

Raised when the PATCH /servers/{id} request that applies attribute changes (name, tags, cloud-init, etc.) returns a non-2xx response. The Scaleway API status code and JSON body are included in the message text.

Solutions

1. Read the embedded status/JSON to see which field the API rejected
2. Validate wished_server attributes against the Scaleway API docs (only name, tags, and a few fields are patchable)
3. Confirm the server id is current and the token has write scope
4. Retry after the server exits any in-progress task

- name: Patch attributes
  scaleway_compute: ...
  register: p
  retries: 2
  delay: 10
  until: not p.failed

When it happens

Trigger: server_change_attributes issues compute_api.patch('servers/%s' % id, data=patch_payload) and response.ok is false — e.g. 400 invalid patch payload, 401 bad token, 404 server deleted, or immutable field modification.

Common situations: Trying to patch read-only attributes, sending tags in the wrong format, stale server id, or token without write permission.
