HTTP 422 errors using system_prune and image_prune

[gu1ll0me]

First, thank you for your work on this MCP server.

I tried to use the arcane_image_prune and arcane_system_prune tools today with Hermes, but the agent receive an HTTP error 422 :
(Arcane container logs)

Jun 23 19:51:39.047 INF Unprocessable Entity request.method=POST request.host=X.X.X.X:3552 request.path=/api/environments/0/images/prune request.query="" request.params=map[id:0] request.route=/api/environments/:id/images/prune request.referer="" request.length=13 response.latency=293.092935ms response.status=422 response.length=226

If I use the Scalar tool in the API reference section to test the images prune, it works :

Jun 23 19:53:23.837 INF Incoming request request.method=POST request.host=X.X.X.X:3552 request.path=/api/environments/0/images/prune request.query="" request.params=map[id:0] request.route=/api/environments/:id/images/prune request.referer=http://X.X.X.X:3552/api/docs request.length=76 response.latency=340.701376ms response.status=200 response.length=142

• the volume_prune and network_prune works great via the MCP server (response.status=200) with Hermes
• all permissions are checked for the Arcane API key
• ARCANE_TOOL_PRESET=full
• Arcane server v2.1.0

I'm I missing something ?
