/api/method/frappe.client.insert Returns 404 in CRM UI (Frappe v15, Local IP Setup)

Hi everyone,

I’ve installed the Frappe CRM app on my Frappe v15 production setup. Everything is served over local IP (http://10.52.10.200) without any custom domain or HTTPS.

However, when I try to create a Lead using the CRM UI, I get the following errors in the browser console:

  • POST /api/method/frappe.client.insert 404 (Not Found)
  • Uncaught (in promise) Error: /api/method/frappe.client.insert DoesNotExistError
  • The UI also shows Internal Server Error on form submission.
