SQLite error: foreign key mismatch (fk incompativeis) when trying to do an INSERT

I'm trying to create a Associative Entity (N: N) in SQLite like this:

  

[Pet --- < VaccinePet> Vaccine]

And, here is my Associative Entity code

CREATE TABLE  VACINAPET (
        vp_data TEXT NOT NULL,
        vp_is_aplicada INTEGER DEFAULT 0,
        fk_pet INTEGER,
        fk_vacina INTEGER,
        FOREIGN KEY (fk_pet) REFERENCES pet (pet_id),
        FOREIGN KEY (fk_vacina) REFERENCES vacina (vacina_id),
        PRIMARY KEY (fk_pet, fk_vacina) 
);

The code for my Pet entity:

CREATE TABLE PET (
        pet_id INTEGER PRIMARY KEY AUTOINCREMENT,
        pet_nome TEXT NOT NULL,
        pet_genero INTEGER DEFAULT 0,
        pet_foto_perfil TEXT,
        pet_peso INTEGER DEFAULT 0,
        pet_dt_nasc TEXT,
        fk_tpanimal INTEGER,
        fk_raca INTEGER,
        FOREIGN KEY (fk_tpanimal) REFERENCES TIPOANIMAL (tpanimal_id),
        FOREIGN KEY (fk_raca) REFERENCES RACA (raca_id)
);

And the code of my entity Vaccine:

CREATE TABLE VACINA (
        vac_id INTEGER PRIMARY KEY AUTOINCREMENT,
        vac_validade TEXT NOT NULL,
        fk_tipo INTEGER,
        FOREIGN KEY (fk_tipo) REFERENCES tipovacina (tpvac_id)
);

BUT, I get this error here:

  

foreign key mismatch - "VACINAPET" referencing "vaccine": INSERT INTO   VACINAPET (vp_data, vp_is_applied, fk_pet, fk_vacina) VALUES   ('23 / 05/2018 ', 0, 1, 1);

When I try to use the following INSERT command:

  

INSERT INTO VACINAPET (vp_data, vp_is_applied, fk_pet, fk_vacina)   VALUES ('23 / 05/2018 ', 0, 1, 1);

What could be wrong?

NOTE: I have data in the Pet and Vaccine tables, they are not empty data
