Why axios post doesn't send cookies?

Question

When i use postman to send request to my api, sessionId doesnt change, and all work good. But, when i use axios to request on api, sessionId change with every single request. In axios config i set withCrendentails: true, and it doesnt help.

nest config (main.ts)

async function bootstrap() {
    const app = await NestFactory.create(AppModule);
    app.enableCors({
        origin: true,
        credentials: true,
    })
    app.use(session({
            secret: SESSION_SECRET,
            resave: false,
            saveUninitialized: true,
            cookie: {secure: false, maxAge: 360000, sameSite: 'strict'},
        })
    )
    app.setGlobalPrefix('api')
    await app.listen(8000);
}

nest controller

@Post()
    async addToCart(@Body() body: AddToCartDto, @Session() session: Record<string, any>, @Res() res: Response, @Req() req: Request) {
        const {productId, quantity} = body
        const cart = session.cart || {items: [], totalPrice: 0}
        console.log(req)

        const existingItem = cart.items.find((item) => item.id === productId);
        if (existingItem) {
            existingItem.quantity += quantity;
        } else {
            const product = await this.productsService.findOne(productId)
            const newItem = { id: productId, title: product.title, quantity, price: product.priceUAN };
            cart.items.push(newItem);
        }
        cart.totalPrice = cart.items.reduce((total, item) => total + item.price * item.quantity, 0);
        session.cart = cart
        res.json({cart})
    }

client side code

export const addToCart = (productId: number, quantity: number): ThunkType => async dispatch => {
    try {
        const data = {productId, quantity}
        const config = {
            headers: {
                "Content-type": "application/json1",
            },
            withCredentials: true,
        }
        const response = await axios.post(`${process.env.REACT_APP_API_URL}/cart`, data, config)
        dispatch({type: SET_CART_SUCCESS, cart: response.data.cart})
    } catch (e) {
        console.log(e)
    }
}
