sequelize returns empty array at querying - node.js

Question

doesn't matter if I try findOne() or findAll()
I get : []
empty array.
the query being called for findAll() is:
SELECT "id", "password", "firstName", "lastName", "email", "phone", "roleId", "userId", "createdAt", "updatedAt" FROM "Users" AS "Users";
while when I manually use in pgadmin cli this query: select * from Users;
I get all the rows of the table.
could you please advise?
