How can i get token auth token in login api?

Iam trying to get auth token in login api but on success login api provides me full name but authToken is missing. It creates problem for me to use report relevant apis now because it shows this error below

** exception: ‘frappe.exceptions.AuthenticationError’,**
** exc_type: ‘AuthenticationError’,**
** exc: ‘[“Traceback (most recent call last):\n File \“apps/frappe/frappe/\”, line 101, in application\n validate_auth()\n File \“apps/frappe/frappe/\”, line 607, in validate_auth\n raise frappe.AuthenticationError\nfrappe.exceptions.AuthenticationError\n”]’**
