For future reference, this function is referred to here: https://www.advancedcustomfields.com/resources/acf-validate_save_post/

It will work if you use the selector within the input name. Should be something such as acf[field_5b1e124565677].

acf_add_validation_error( 'acf[field_5b1e124565677]', 'Required' );
