"Invalid Character \ud835" when used in React Native Android app.

[jsh8w]

Hello.

We're seeing the following error when using the contentstack JS dependency in a React Native 0.66.4 project. Interestingly, this issue only occurs when the app is run in debug mode. When the app is run in release mode, the issue does not appear.

I've done a fair amount of debugging today and found that when I remove the import of contentstack, the app works correctly and we don't see the error. This leads me to think it's something in the contentstack dependency.

We can see that the \ud835 unicode symbol renders as � and we can see this symbol within the contentstack directory in node_modules.

I'm at a bit of a loss as to what is actually throwing this particular error and why.

Any help would be greatly appreciated.

Thanks.

Hi @jsh8w ,

Thanks for raising the issue, we will look into this issue and will let you know once we resolve this issue.

Thanks @uttamukkoji.

We have done some further digging this morning and found that v3.14.0 works in our React Native project and we no longer see the issue. So it is something that has been introduced in v3.15.0 that is causing the issue.

We will downgrade to v3.14.0 in the meantime whilst you are looking into the issue.

Thanks.

Just a note that we've just seen this in a Next.js project on Safari iOS 13 (iOS 14 is fine). Any updates on a fix @uttamukkoji?
