Can not run app in device

[ducnmisbk]

Hi @twelve17 ,

Would you please give me some help?
I'm getting errors when trying to run app in device.
(Run app in simulator is ok)

Output log:

Did you ever get this solved? I am having the same issue

@agoodmiller : I resolved with below configs.

Where does it need to replace configs?
