Console: modal-typed actions resolve `target` as an object — submit fails with GET /meta/object/<target> 400

[os-zhuang]

Summary

Submitting a type: 'modal' action fails with "Error loading form — Bad Request". The Console resolves the action's target as an object name and issues GET /api/v1/meta/object/<target>, which 400s because target names a page, not an object.

Per the spec, that is the wrong lookup:

type: 'modal' — target is required (the modal/page name to open).
— @objectstack/spec/dist/action.zod-*.d.ts, Action target docs

Environment

• @objectstack/* 16.1.0
• Node 22.22.3, dev server (objectstack dev), wasm sqlite
• App: HotCRM (open source, https://github.com/objectstack-ai/hotcrm)

Steps to reproduce

1. Declare a modal action and a matching page:

export const LogCallAction: Action = {
 name: 'log_call',
 label: 'Log a Call',
 type: 'modal',
 target: 'log_call', // ← the modal PAGE name, per spec
 body: { language: 'js', source: `/* insert a record */`, capabilities: ['api.write'] },
 locations: ['record_header'],
 params: [
 { name: 'subject', label: 'Call Subject', type: 'text', required: true },
 { name: 'duration', label: 'Duration (minutes)', type: 'number', required: true },
 { name: 'notes', label: 'Call Notes', type: 'textarea' },
 ],
};

// registered page
export const LogCallPage: Page = { name: 'log_call', type: 'utility', /* … */ };

2. Open a record, click Log a Call.
3. The modal opens and the params form renders correctly from params.
4. Fill it in, press 确认 / Confirm.

Expected

The action body executes with the collected input, and the record is written.

Actual

The modal body is replaced with:

Error loading form
Bad Request

Network:

GET /api/v1/meta/object/log_call → 400 Bad Request

The body never runs; nothing is written.

Scope

Reproduced on every modal action in the app — log_call, log_meeting, create_campaign, escalate_case, close_case, mass_update_stage, send_email. A freshly authored one fails identically (GET /api/v1/meta/object/schedule_followup → 400), so it is not about any particular page definition.

The params form rendering correctly but the submit path resolving target differently suggests two code paths that disagree about what target means: the render path treats it as a page (correct), the submit path as an object.

Impact

Modal actions are the natural shape for "collect a couple of fields and write something" — the most common custom action in a business app. None of them can be completed. The only workaround we found is to re-author each one as a type: 'flow' screen flow.

Screen flows are also un-completable from the Console (Submit never calls the resume endpoint) — filed separately. Together these make every interactive custom action in the app non-functional.
