Need Help with WooCommerce Subscription Auto-Renewal Issue

I’m facing two issues with my WooCommerce store:

1. Auto-renewal problem: My subscription products aren’t renewing automatically; instead, they’re getting canceled upon renewal. How can I fix this?
2. Error message: On the order page, I saw this note: “You passed an empty string for ‘customer’. We assume empty values are an attempt to unset a parameter; however ‘customer’ cannot be unset. You should remove ‘customer’ from your request or supply a non-empty value.” How do I resolve this?

Any help would be appreciated. Thank you!
