React native different behaviour between debug mode and normal mode

hi I have a really complicated problem. So I created a new repo for this problem at github. So you can clone it and see what the problem is.
https://github.com/guitar9/hafas-client-example
I am using https://github.com/public-transport/hafas-client in this project to get train and railway station informations.

client.journeys(münchenHbf, münchenPassing)
.then((response)=>{
  console.log('===============response=====================');
  console.log(response);
  console.log('====================================');
})
.catch(console.error)

the request is in

node_modules/hafas-client/lib/request

Problem is in debug mode everything works fine (shake phone and start remote JS Debugging), but when i stop JS Debugging i get Error 'PARSE'.
So i looked up in request.js and logged out request and response in debug mode and not in debug mode.
Request Debug Mode

    }
}

Response Debug Mode
all informations. everything okay.
Request not in debug mode

    "query": {
        "checksum": "0d8186da7b06f9cc094075a2a6e21b00"
    }
}

Response not in debug mode

{
    "ver": "1.16",
    "ext": "DB.R15.12.a",
    "lang": "eng",
    "id": "",
    "err": "PARSE",
    "svcResL": []
}

I have compared the requests. Here you can see the difference between the two request. https://www.diffnow.com/?report=pvuq7 The problem is outDate, outTime and checksum. Somebody can help me?
