After I catkin_make to build the project,
I find the execution file in build/examples folder.

when I execute the file it shows

./example_KafkaConsumer_Simple
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Aborted (core dumped)

Could anyone help?
Thanks in advance!
