The error value is not generated on compile, but on execution. If the app_uart_put function, on execution, isn't executed properly there are checks within the code that will assign it an error code. Typically you would write code that returns an error code as

err_code = app_uart_put();
APP_ERROR_CHECK(err_code);

In this case an error handler will be called if the app_uart_put function is not successfully executed. If you set the DEBUG flag within the preprocessor symbols, all errors should put your program in a loop, in which you can try and determine the cause of your error when using debugging.

If the function is executed properly the return value will be 0, which is defined as NRF_SUCCESS.

Yeah, it should also be an output, just as you said. It compiles without an error, so I opened this question to discuss possible reasons

You say you only see the 1 outputted from line 74? You should also see something from line 87. The app_uart_put() function has a 32 bit return value, have you checked if it produces an error?
