Undefined is not an object (evaluating '_reactNativeMixpanel.Mixpanel.sharedInstanceWithToken')

[jorge-sanz]

I am getting this error with this code:

import { Mixpanel } from 'react-native-mixpanel';
...
Mixpanel.sharedInstanceWithToken(TOKEN);
Mixpanel.track("New order");

Any idea of how to solve it? Thank you so much! 🙂

[syafiq90]

Mixpanel.default.sharedInstanceWithToken(TOKEN);

All must be Mixpanel.default

@syafiq90 it's working right now for me. Not sure how I fixed it. I restarted the project again.

hey guys, we are getting the same issue:

Mixpanel.sharedInstanceWithToken("APIxxxxxx")

Error: `TypeError: Cannot read property 'sharedInstanceWithToken' of undefined.

Versions:

• react-native-mixpanel: 1.1.1
• pod 'Mixpanel', '~> 3.3.3'
• react-native: 0.55.3

When console logging Mixpanel the functions show up as expected:

Let me know if you need any more info!

Cheers

It looks like RNMixpanel is undefined in node_modules/react-native-mixpanel/index.js line 4:

const { RNMixpanel } = NativeModules

I forgot to link it in xcode 🤦‍♂️:

Go to node_modules ➜ react-native-mixpanel and add RNMixpanel.xcodeproj In XCode, in the project navigator, select your project. Add libRNMixpanel.a to your project's Build Phases ➜ Link Binary With Libraries

import Mixpanel from 'react-native-mixpanel' instead of var Mixpanel = require('react-native-mixpanel') did it for me. The module now exports a default object and a MixpanelInstance object. Therefore, the above default import should be used or import {MixpanelInstance} from 'react-native-mixpanel' for the new (?) interface

you can use like this, i found in file index.js:

const mixpanel = new MixpanelInstance(TOKEN)
await mixpanel.initialize()
mixpanel.track('my event')

My issue was not in the Javascript, but in this:

Try to import without braces like :

import Mixpanel from 'react-native-mixpanel';
