onUpdated not trigged

I started my codebase with svelte 4 and following code worked fine for my client side validated form but after recent svelte 5 migration onUpdated no longer trigged but onUpdate is trigged.
Any help is appreciated

package.json

 "svelte": "^5.15.0"
"sveltekit-superforms": "^2.22.1",
"zod": "^3.23.8"
    "formsnap": "^1.0.1",

const form = superForm<any>(
    inboxAutomation
      ? {
          ...inboxAutomation,
        }
      : {
          name: "Untitled",
          messages_tree: {...InitialInboxAutomationMessageNode}
        },
    {
      SPA: true,
      resetForm: false,
      dataType: "json",
      validators: zodValidator(inboxAutomationSchema),
      onUpdated: async ({ form: f }) => {
        console.log("🚀 ~ onUpdated: ~ f:", f)
        if (f.valid) {
          try {
            //return submitAutomation(f.data);
          } catch (e) {
            console.log("error", e);
          }
        } else {
          console.log("form is invalid", f.errors);
         
          }
        }
      },
    },
  );
