Hi everybody. I am currently taking my first steps with Odoo, installed locally.

The login (authentication) via Postman fails. 

Does anyone have a tip for me what is wrong?

Postman Get Request:  http://localhost:8070/web/session/authenticate

JSON raw code:

{    "jsonrpc": "2.0",     "params": {        "db": "mydbname",         "login": "myuser",         "password": "mypw"    }}

The result:

{    "jsonrpc": "2.0",    "id": null,    "error": {        "code": 200,        "message": "Odoo Server Error",        "data": {            "name": "builtins.KeyError",            "debug": "Traceback (most recent call last):\n  File \"/usr/lib/python3/dist-packages/odoo/http.py\", line 1722, in _serve_db\n    return service_model.retrying(self._serve_ir_http, self.env)\n  File \"/usr/lib/python3/dist-packages/odoo/service/model.py\", line 133, in retrying\n    result = func()\n  File \"/usr/lib/python3/dist-packages/odoo/http.py\", line 1749, in _serve_ir_http\n    response = self.dispatcher.dispatch(rule.endpoint, args)\n  File \"/usr/lib/python3/dist-packages/odoo/http.py\", line 1953, in dispatch\n    result = self.request.registry['ir.http']._dispatch(endpoint)\n  File \"/usr/lib/python3/dist-packages/odoo/addons/base/models/ir_http.py\", line 222, in _dispatch\n    result = endpoint(**request.params)\n  File \"/usr/lib/python3/dist-packages/odoo/http.py\", line 722, in route_wrapper\n    result = endpoint(self, *args, **params_ok)\n  File \"/usr/lib/python3/dist-packages/odoo/addons/web/controllers/session.py\", line 33, in authenticate\n    pre_uid = request.session.authenticate(db, login, password)\n  File \"/usr/lib/python3/dist-packages/odoo/http.py\", line 986, in authenticate\n    pre_uid = registry['res.users'].authenticate(dbname, login, password, wsgienv)\n  File \"/usr/lib/python3/dist-packages/odoo/modules/registry.py\", line 213, in __getitem__\n    return self.models[model_name]\nKeyError: 'res.users'\n",            "message": "res.users",            "arguments": [                "res.users"            ],            "context": {}        }    }}
