Nativescript crashes "Expected Android API level 21+ but was 30"

Question

My app launches perfectly on my real device and on emulators (both Android 10 - API 29), but when I try to emulate on a Android 11 - api 30, it crashes after splash screen with this error :

I found this article that says you have to update okhttp3 but I don't know how to do this in nativescript, i'm guessing it's in the nativescript/core ?

My environement :

Nativescript version : 7.1.0
Nativescript core : 7.0.3
Nativescript Vue : 2.8.1

Thanks all for your help

This is fixed in OkHttp https://github.com/square/okhttp/issues/6569 in 3.12.13 (Legacy Android), 3.14.7 (Android 5+) and 4.9.1 https://github.com/square/okhttp/blob/edf477cb4e7b1d59c6e3e5ac00870619340ce990/docs/changelog_3x.md#version-3147

See https://github.com/NativeScript/canvas/issues/32 for a discussion and example of updating the dependency
