Pabbly thankyou page issue - undefined (reading 'subscription')

Hi Team,

I am facing some issue on Pabbly thankyou page as user successfully pay from the checkout page and subscribed successfully on the pabbly. Once user redirects to the thankyou page then it shows the blank screen. If we check console error then it shows
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'subscription')

Kindly have a look and share your thoughts on it how we can resolve this

We have isolated the thank you page issue to having a blank value in the charge for the trial period when editing the product plan.

@Akanksha Jain The issue occurs once we keep the free trial price blank. If we add $ 0.5 in the free trial then it works fine and shows the thank you page perfectly. However, we would like to provide a trial period free of cost, therefore, the trial price should be 0 which is not advisable as per pabbly validations.

I am attaching the screenshots, please have a look.
