api.login example issue

[admarrs]

Following the docs and implementing api.login(email text, pass text) as outlined below. I get the following:

> curl -X 'POST' 'http://127.0.0.1:8082/rpc/login' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{"email": "[email protected]", "pass": "foobar"}'

{"hint":"If a new function was created in the database with this name and parameters, 
try reloading the schema cache.","message":"Could not find the api.login(email, pass) 
function or the api.login function with a single unnamed json 
or jsonb parameter in the schema cache"}

What am I missing here - I can get it to work if I change the return type to json and return to_json(result) though that doesn't fell right.

Function implementation is:

create or replace function
api.login(email text, pass text) returns basic_auth.jwt_token as $$
declare
  _role name;
  result basic_auth.jwt_token;
begin
  -- check email and password
  select basic_auth.user_role(email, pass) into _role;
  if _role is null then
    raise invalid_password using message = 'invalid user or password';
  end if;

  select sign(
      row_to_json(r), 'reallyreallyreallyreallyverysafe'
    ) as token
    from (
      select _role as role, login.email as email,
         extract(epoch from now())::integer + 60*60 as exp
    ) r
    into result;
  return result;
end;
$$ language plpgsql security definer;

My bad - schema cache issue. docker kill -s SIGUSR1 <container id> sorted it. You can close this.
