No callback found

Question

Hello,I am using the React Native SDK.Since the last upgrades (from 4 to 6), I get this type of error when calling Intercom.sendTokenToIntercom in JS side. WARN  [Error: Error in sendTokenToIntercom] ERROR  Invariant Violation: No callback found with cbID 31610 and callID 15805 for  IntercomModule.sendTokenToIntercom - most likely the callback was already invoked. Args: '[true]', js engine: hermesI did : - Full cleaning of cache (node_modules, xcode...etc)- downgrading from 4 to 6.0.1.No success.I don’t know if it comes after upgrades of another packages.But the rest works well (messenger...etc). Except this call.If you have any idea?​​​​​​​Thank you ! React Native 0.72.5Xcode 15iOS 17

Hi @Erwan!This looks like an issue that might be specific to your app’s unique setup. You’ll want to chat with our Support team for an issue like this. I’m going to send this conversation their way and they will reach out to you in a day or two via the email address that you signed up with.

Hi @Huw MartinIt looks like this type of issue is normally due to your app running thesendTokenToIntercom call beforethe user is logged into your app. Can you make sure you’re making those calls in the correct order?If you are and you’re still having the issue then I would encourage you to write into our Support team via the Messenger in your workspace or at team@intercom.ioand they can dig into this further with you!
