ora-06575 package or function is in an invalid state pl sql - oracle

Question

I am new to pl sql and i am trying to call a procedure but i am getting the error ora-06575 package or function is in an invalid state.
What do you think i am doing wrong? Thanks
select * from NB_tfr_USERS; --previous table created
create or replace procedure nb_tfr_add_user
(
i_user_name in nb_tfr_users.name%type,
i_address in nb_tfr_users.address%type,
i_birthdate in nb_tfr_users.birthdate%type,
o_userid out nb_tfr_users.id%type,
o_errm out varchar2
) AS
--Variables
l_user_id number;
--Parameters invalid exception
error_params exception;
BEGIN
--validate parameters
--- name can not be empty
--- birthdate can be empty
if i_user_name is null or length(i_user_name) = 0 then
raise error_params;
end if;
--initialize variables
l_user_id := nb_seq_tfr_user_id.nextval;
--insert new user
insert into NB_tfr_USERS (id, name, address, birthdate)
values (l_user_id, i_user_name, i_address, i_birthdate);
--deal with exceptions
exception
when error_params then
o_errm := 'Invalid Parameters!';
dbms_output.put_line(o_errm);
when others then
dbms_output.put_line('Error: '||sqlerrm);
o_errm:=substr(1,150,sqlerrm);
raise;
END NB_tfr_ADD_USER;
call
nb_tfr_add_user(54,'tf','lx',12121989);
So when i try to call the procedure i get the error.

Well, it looks OK - apart from the fact that you incorrectly called the procedure.
Here's a test case.
SQL> create table nb_tfr_users
2 (id number, name varchar2(10), address varchar2(10), birthdate date);
Table created.
SQL> create sequence nb_seq_tfr_user_id;
Sequence created.
The procedure:
SQL> create or replace procedure nb_tfr_add_user
2 (
3 i_user_name in nb_tfr_users.name%type,
4 i_address in nb_tfr_users.address%type,
5 i_birthdate in nb_tfr_users.birthdate%type,
6 o_userid out nb_tfr_users.id%type,
7 o_errm out varchar2
8 ) AS
9 --Variables
10 l_user_id number;
11 --Parameters invalid exception
12 error_params exception;
13 BEGIN
14 --validate parameters
15 --- name can not be empty
16 --- birthdate can be empty
17 if i_user_name is null or length(i_user_name) = 0 then
18 raise error_params;
19 end if;
20
21 --initialize variables
22 l_user_id := nb_seq_tfr_user_id.nextval;
23
24 --insert new user
25 insert into NB_tfr_USERS (id, name, address, birthdate)
26 values (l_user_id, i_user_name, i_address, i_birthdate);
27
28 --deal with exceptions
29 exception
30 when error_params then
31 o_errm := 'Invalid Parameters!';
32 dbms_output.put_line(o_errm);
33
34 when others then
35 dbms_output.put_line('Error: '||sqlerrm);
36 o_errm:=substr(1,150,sqlerrm);
37 raise;
38 END NB_tfr_ADD_USER;

Testing - it shows how you should have called it. As there are 3 IN and 2 OUT parameters, that's what you should have done as well.
SQL> set serveroutput on
SQL> declare
2 l_userid nb_tfr_users.id%type;
3 l_Errm varchar2(200);
4 begin
5 nb_tfr_add_user(i_user_name => 'tf',
6 i_address => 'lx',
7 i_birthdate => sysdate,
8 o_userid => l_userid,
9 o_errm => l_errm);
10 dbms_output.put_Line(l_userid ||' '||l_errm);
11 end;

If you got the error, it - obviously - means that there's something wrong. I don't know what, but - maybe you forgot to create the sequence.
Anyway: after creating stored procedures, check whether everything is OK by running (in SQL*Plus) show err, e.g.
SQL> create or replace procedure p_test is
2 begin
3 insert into abc (id) values (seq_does_not_exist.nextval);
4 end;
5 /
Warning: Procedure created with compilation errors.

Errors for PROCEDURE P_TEST:
LINE/COL ERROR

Or, query user_source:
SQL> select line, text, attribute from user_errors where name = 'P_TEST';
LINE TEXT ATTRIBUTE
----- -------------------------------------------------- ---------
3 PL/SQL: ORA-00942: table or view does not exist ERROR
3 PL/SQL: SQL Statement ignored ERROR

I suggest you do the same and see what's wrong with the procedure.
