    Hi,

    I re-rested the integration with the same base setup but for me this error message was not shown even with full logging enabled.

    That does not mean you are wrong but it could be related to a conflict with another WP plugin or your theme itself.

    Do you have any sandbox site where you can safely activate/deactivate plugins?
    The test would be to disable all plugins except for WooCommerce and GTM4WP and then place a test order to see what happens.

    Also: if you turn off the “Cart content in data layer” option, the error will go away

    Hi @duracelltomi!

    Thanks for your response, for now, this error is not appearing anymore, If its come again i will try to excavate what exactly the cause of the error, Might possible the confliction cause.

    Regards
    Mubashar
