SPI slave read data into buffer on stm32?

I'm trying to set communication between esp32 (master) and stm32 (slave) over SPI. esp32 is running under micropython and sends four bytes, for example spi.write_readinto(b'\x31\x32\x33\x34', buf)

stm32' code is here (instead of this i use SPI_InitDef.SPI_NSS = SPI_NSS_Soft;)

void SPI_Init(void) {
    ...

    //  initialize SPI slave
    // for slave, no need to define SPI_BaudRatePrescaler
    SPI_InitDef.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
    SPI_InitDef.SPI_Mode = SPI_Mode_Slave;
    SPI_InitDef.SPI_DataSize = SPI_DataSize_8b; // 8-bit transactions
    SPI_InitDef.SPI_FirstBit = SPI_FirstBit_MSB; // MSB first
    SPI_InitDef.SPI_CPOL = SPI_CPOL_Low; // CPOL = 0, clock idle low
    SPI_InitDef.SPI_CPHA = SPI_CPHA_2Edge; // CPHA = 1
    SPI_InitDef.SPI_NSS = SPI_NSS_Hard; // use hardware SS
    SPI_InitDef.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_64; // APB2 72/64 = 1.125 MHz

    SPI_InitDef.SPI_CRCPolynomial = 7;
    SPI_Init(SPI1, &SPI_InitDef);

    SPI_Cmd(SPI1, ENABLE);

    NVIC_EnableIRQ(SPI1_IRQn);
    //Тут мы разрешаем прерывание по приему
    SPI_I2S_ITConfig(SPI1, SPI_I2S_IT_RXNE, ENABLE);
}

void main() {
    /* Setup SysTick Timer for 10ms interrupts  */
    if (SysTick_Config(SystemCoreClock / 100))
    {
    /* Capture error */
    while (1);
    }
    /* Configure the SysTick handler priority */
    NVIC_SetPriority(SysTick_IRQn, 0x0);

    SPI_Init();

    while(1) {
        while(!SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE));
        for (u8 i=0; i<4; i++) {
            printf("0x%02x ", SPI_I2S_ReceiveData(SPI1));
        }
        printf("\r\n");
    }
}

But when I send four bytes 0x31 0x32 0x33 0x34 (analyzer confirms bytes were sent) and my stm gets only 0x31 0x32 0x31 0x32

UPD I use std periph library and SPI_I2S_ReceiveData is a native method to read byte from SPI.

uint16_t SPI_I2S_ReceiveData    (   SPI_TypeDef *   SPIx     )  
Returns the most recent received data by the SPIx/I2Sx peripheral.

Parameters:
SPIx,:  To select the SPIx/I2Sx peripheral, where x can be: 1, 2 or 3 in SPI mode or 2 or 3 in I2S mode or I2Sxext for I2S full duplex mode.
Return values:
The     value of the received data.

uint16_t SPI_I2S_ReceiveData    (   SPI_TypeDef *   SPIx     )  
Returns the most recent received data by the SPIx/I2Sx peripheral.

Parameters:
SPIx,:  To select the SPIx/I2Sx peripheral, where x can be: 1, 2 or 3 in SPI mode or 2 or 3 in I2S mode or I2Sxext for I2S full duplex mode.
Return values:
The     value of the received data.

But maybe I exit out from IRQ before all data are read. I found to run the while loop until the transmission of the last byte is complete
