Login for access token 422 Validation Error FastApi

I want make autorization on my site using this code (It is not important for me to use this particular authorization option. If you have other options for implementing authorization on the site, I will be glad to consider them)
def get_db():
db = SessionLocal()
try:
yield db
finally:
db.close()

SECRET_KEY = "somekeyfasfascsacs"
ALGORITHM = "HS256"

bcrypt_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_bearer = OAuth2PasswordBearer(tokenUrl="auth/token")

db_dependency = Annotated[Session, Depends(get_db)]

def authenticate_user(username: str, password: str, db: db_dependency):
user = db.query(Users).filter(Users.username == username).first()
if not user:
return False
if not bcrypt_context.verify(password, user.hashed_password):
return False
print(type(user))
return user

def create_access_token(username: str, user_id: int,
expires_delta: Optional[datetime.timedelta] = None):

encode = {"sub": username, "id": user_id}
if expires_delta:
expire = datetime.datetime.utcnow() + expires_delta
else:
expire = datetime.datetime.utcnow() + datetime.timedelta(minutes=15)
encode.update({"exp": expire})
return jwt.encode(encode, SECRET_KEY, algorithm=ALGORITHM)

async def get_current_user(token: Annotated[str, Depends(oauth2_bearer)]):
try:
payload = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM])
username: str = payload.get("sub")
user_id: int = payload.get("id")
user_role: str = payload.get("role")
if username is None or user_id is None:
raise HTTPException(status_code=status.HTTP_401_UNAUTHORIZED, detail="Could not validate user")
return {"username": username, "id": user_id, "user_role": user_role}
except JWTError:
# When authorizing using a button and trying to use other functions,
# it gives this error
raise HTTPException(status_code=status.HTTP_401_UNAUTHORIZED, detail="Could not validate user")

@router.post("/token")
async def login_for_access_token(response: Response, form_data: OAuth2PasswordRequestForm = Depends(),
db: Session = Depends(get_db)):

user = authenticate_user(form_data.username, form_data.password, db)
if not user:
return False
token_expires = datetime.timedelta(minutes=60)
token = create_access_token(user.username,
user.id,
expires_delta=token_expires)

response.set_cookie(key="access_token", value=token, httponly=True)

return True



But I get this error:





If you log in through the Autorize button, it doesn’t give you an error, but when you try to use other functions, the site gives you a 401 Unautorize error.
