Dataplane exits at startup if config file does not exist

[ema-pe]

I noticed that when I start the dataplaneapi for the first time, if the default dataplaneapi.yaml config file is not found (or doesn't exist), the program creates a new one. However after that it still doesn't start serving the Data Plane API immediately. I have to restart it once more for it to actually start serving. See the logs below. Is this intended behavior?

$ dataplaneapi \
          --host 0.0.0.0 \                                                                                                                                              
          --port 5555 \
