I am stuck at the same error on version 4.1.0, too.
As you say, the error shows up regardless of the projects.
In my case, downgrading to 4.0.2 fixed the problem.

I think this issue should be related to some of the changes on 4.1.0.
If I find any useful information, I will share it here.

Hi @domzinhuu,

[domzinhuu]

+1 I'm having the exact same problem too.

Hi @domzinhuu, @mintyweazel, @andresggarcia,

I was able to reproduce the problem with old versions of tns-ios, but it works fine with latest version of tns-ios. So I'm suspecting your tns-ios version is not the latest one. You can check it inside package.json file. If this is the case I'm suggesting to update to latest tns-ios version. To do it execute the followings:

rm -rf platforms
tns platform add ios@latest

Let's us know if this works on your side.

Hello @Fatme
i dont try use ios@latest but i try remove platform exclude the platform folder and add platform again and nothing, but i'll try again when update nativescript, because i make a downgrade to try the tips of @mintyweazel and the tips resolve the problem for me.

i'll update again and try your tips and post here the result.

Hi @Fatme,

I tried your solution with the command tns-android instead of tns-ios, but it did not work. In that case, the android runtime version is 4.1.3 and the cli version is 4.1.1, both of which are the latest version.

Hi @mintyweazel,

I wasn't able to reproduce the problem for android. Can you please send us a log file (just execute the command with --log trace) or give us exact steps to reproduce the problem.

[domzinhuu]

Hi @Fatme

I update again my nativescript CLI and try your tips with android add ios and android plat with @latest but not work i had the same problem. My solution for now was the tips of @mintyweazel

I am stuck at the same error on version 4.1.0, too.
As you say, the error shows up regardless of the projects.
In my case, downgrading to 4.0.2 fixed the problem.

Hi, I got the same problem for tns debug android with [email protected]
Here is my output of tns debug android --log trace. I removed some output, which is marked with [...].
The downgrad to v4.0.2 by running npm i -g [email protected] resolved the problem for me.

Edit: I forgot to add the link to my output 🤦‍♂️ https://pastebin.com/yNxkia0C
