Why do I receive an error while building code generated for the STM32F4xxx target using Embedded Coder in MATLAB R2023b?

I am generating code and trying to build it for the STM32F4xxx target using Embedded Coder in MATLAB R2023b. While doing so, I am receiving the following error:

C:/Users/<username>/Downloads/esc1/esc/esc/codegen/Core/Src/stm32f4xx_it.c:210:23: error: 'hdma_usart2_rx' undeclared (first use in this function) 210 |   HAL_DMA_IRQHandler(&hdma_usart2_rx);

Why am I getting this error, and how do I resolve this?

You seem to be using a different version of the STM32CubeMX software than expected. Please do the Hardware Setup as explained in the documentation below, and check which version of STM32CubeMX is expected:
