1 month ago Hi @nunoliveira12,
We have introduced a polyfill for addressing this issue, but the current conditions for which it applies are not precise, and in some setups like yours the problem still occurs. We will introduce an official fix for this problem.
In the meantime, if this is a blocker for you, I believe you could use the following workaround:
1. Install patch-package and big-integer in your project.
2. Configure patch-package by adding this script to your package.json:
"scripts": {
+ "postinstall": "patch-package"
}3. Create a folder named patches in your project root directory
4. Create a file ./patches/@datadog+mobile-react-native+2.4.4.patch with the following content:
diff --git a/node_modules/@datadog/mobile-react-native/src/polyfills.js b/node_modules/@datadog/mobile-react-native/src/polyfills.js

This should force the polyfill to always be applied, by explicitly and globally defining BigInt with the big-integer library.
Let me know if it works for you!
I will keep you posted on this matter, and notify you when the release with the fix is out.
Does that sound good to you? :)

Stack trace
ReferenceError: Property 'BigInt' doesn't exist, js engine: hermes
Reproduction steps
Not able to run package version 2.3.6 on Xcode 16 made me install the new version.
After Installing latest version of dd-sdk-reactnative (2.4.4) I have errors of BigInt since I think (?) that RN <0.70 does not support it.
I have the errors as soon as I import anything from Datadog packages.
