Hi Team,

I am getting the below shown error while trying to connect my device.

Proxy error: Could not proxy request /api/devices from localhost:8080 to http://localhost:31337/ (HPE_INVALID_CONSTANT).

Note: Jailbroken iphone connected via USB.
The grapefruit is installed and is up and running on the below IPs;

App running at:

Local: http://localhost:8080/
Network: http://192.168.0.132:8080/

Can you help me with some hints on how to proxy my localhost:8080 (my mac machine) to http://localhost:31337/ (jailbroken iphone)?

It seems like a server side error. Please attach the console logs

Note that the development build is not optimized.
To create a production build, run npm run build.

There are three tabs. This one is the WebPack and it does not provide the right information.

You need to find the one like this:

> grapefruit-server@0.7.0 dev H:\Grapefruit\server
> nodemon

[nodemon] 2.0.2

Hi ChiChou,

The issue got resolved, it was some nodejs error. It works fine.
Thank you :)

One query: Is it always better to run the production build for testing? or is the development build have any restrictions in place at present?

Answer 5 · 2020-07-14T02:56:07.000Z

It's not recommended to use the current codebase since it's in progress and unstable. Please wait for the Beta release, though I can't guarantee the timetable

So the production build is avaliable now. Please do not use the development environment unless you know exactly what you're doing
