I am willing to make hafas-client work in react-native without any
modifications. I will create a branch for you to try.

I have different bodys in debug mode and in production mode. I have uploaded a comparssion between the two bodys. |
Which debug and production mode are you referring to?
This is very weird. Will try to figure out why. In the meanwhile, can you try to, instead of the |
If I run my app on a device I can open dev menu and start debugger mode on device. |

Can you log the response by and send it? The appropriate place would be here: Line 67 in c78f64d You can log the response like this: return fetch(url, req)
.then((res) => {
err.statusCode = res.status
if (!res.ok) {
err.message = res.statusText
throw err
}
return res.text()
})
.then((raw) => {
console.error(raw)
return JSON.parse(raw)
})
.then((b) => { |

I've had a look into this once more. I successfully ran I assume all other errors are related to specifics of your local setup. I'm willing to help debug this, but only with comprehensive info. |
Hopefully prevents situations like in #56 in the future. #56 (comment)

I will close this. Please reopen with more details if you still have issues. |
