TypeError: customerData.getInitCustomerData is not a function

[Berman59]

... from "Klaviyo_Reclaim/js/customer.min.js". Getting this error on a Magento 2.3.7 test environment. I don't see getInitCustomerData in Magento 2.3.7's customer-data.js, is it because this version is not supported anymore...?

Also seeing this error running M2.4.3-p1

Confirm also seeing this on 2.3.7

For the comments above, can you also supply which version of the Klaviyo extension you are using?

[diyontheweb]

Hi @Jaeto. We have tried 4.0.5 and 4.0.2 on Magento 2.3.7.

[fidellakis-coolibar]

We fixed this by ensuring any theme overrides from Magento_Customer module has all methods from extending class.

Hi. I have created a module for fixing this issue.

@fidellakis-coolibar Have you found getInitCustomerData() function in your Magento installation? I noticed there is not any modules that add mentioned function.

[fidellakis-coolibar]

@guentur check vendor/magento/module-customer/view/frontend/web/js/customer-data.js. It's there for me. What version of Magento are you running.

[guentur]

@fidellakis-coolibar My project uses Magento 2.3.4. I have found there is not required function (getInitCustomerData()) in vendor/magento/module-customer/view/frontend/web/js/customer-data.js. I will change my module to add this function instead of just removing calling this function in Klaviyo module
