SQLite view empty


I’m using SQLite3 and DB Browser for manage my database for a web project, it’s a convention register manager. There I have this table

CREATE TABLE "Tickets" (
    "code"  TEXT,
    "name"  TEXT NOT NULL,
    "category_id"   INTEGER,
    "status"    TEXT NOT NULL,
    FOREIGN KEY("category_id") REFERENCES "TicketCategories"("id"),
    PRIMARY KEY("code")
);

Here I have a foreign key with the table TicketCategories, this other table:

CREATE TABLE "TicketCategories" (
    "id"    INTEGER,
    "name"  TEXT NOT NULL,
    "price" DECIMAL(10, 2) NOT NULL,
    "description"   TEXT,
    PRIMARY KEY("id" AUTOINCREMENT)
);

The point is, I want to made a view where the "category_id" it appear as the name of the ticket category in "TicketCategories" table, I made this view for do that:

CREATE VIEW TicketInfo AS
SELECT 
    Tickets.code,
    Tickets.name AS ticket_name,
    TicketCategories.name AS category_name,
    Tickets.status
FROM 
    Tickets
JOIN 
    TicketCategories ON Tickets.id_cat = TicketCategories.id;

But when I run it, the view appears empty, without any data:
enter image description here

I’ve already made another similar view and it works, I dont know why this view don’t work. I tried do some changes and nothing.

I have tried to change the view creation code like this

CREATE VIEW TicketInfo AS
SELECT 
    t.code,
    t.name AS ticket_name,
    tc.name AS category_name,
    t.status
FROM 
    Tickets t
JOIN 
    TicketCategories tc ON t.id_cat = tc.id;

and I tried to use LEFT JOIN, but it didn’t solve anything
