TypeError: Cannot set property 'distinctId' of undefined when call identify method

[klalex]

After signup I call mixpanel.identify(email). It logs I see LOG [Mixpanel] Identify '...'. But then immediately get this error:

TypeError: Cannot set property 'distinctId' of undefined.

I've checked email has value. So it's not undefined. Even in mixpanel logs email is displayed for identify.

mixpanel.track() works as expected though.

hi @klalex , do you mind sharing the full log and the code snippet that can reproduce the issue?

[klalex]

@zihejia I used example from docs:

const mixpanelToken = '...';
const mixpanel = new Mixpanel(mixpanelToken, false);
mixpanel.setLoggingEnabled(true);
mixpanel.init();
mixpanel.identify(email);

Also when I downgraded to version 2.4.1 it works now. So something wrong with version 3.0

[zihejia]

hi @klalex , would you like to try 3.0.2?

I got the same error.
It should be "await mixpanel.init();" because the init function is an async function.
