Based on the information provided in the knowledge sources, I don't have enough specific details to directly address why you're encountering the "Cannot read properties of undefined (reading 'clear')" error in the mixpanel.reset() function. However, I can provide some general insights about the reset() function in Mixpanel and suggest a potential cause for this error.The reset() function is used to clear data attributed to a user when they log out. It's typically called to handle multiple users on a single device. Here's what the documentation says about reset(): Mixpanel SDKs: Javascript mentions: LBKS// your user logs out and tracks a log out event mixpanel.track('log out');LBKS// generate new cookie with new distinct_id mixpanel.reset();LBKSThe error you're encountering suggests that this['persistence'] is undefined when the clear() method is called. This could potentially happen if the Mixpanel object hasn't been properly initialized or if the persistence configuration is not set correctly.To troubleshoot this issue, you might want to check: 1. If you've properly initialized Mixpanel with a valid project token. 2. If you're calling reset() on a valid Mixpanel instance. 3. If you've set any custom persistence configurations that might be affecting this.For example, when initializing Mixpanel, you can set the persistence configuration like this: LBKSmixpanel.init('YOUR_PROJECT_TOKEN', { persistence: 'localStorage', });LBKSIf you're still encountering issues, you might want to check the Mixpanel initialization and configuration in your code, or reach out to Mixpanel's support team with more details about your specific implementation.
