Thanks for your contribution @LimarenkoDenis! Can you update the tests as well?

@pr-Mais Looks like pipeline is failing even in typo fix change - #597

Sorry, I'm not able to update tests here

Do you mind merging these changes and updating the Firebase extension?

Hi,
I tried implementing this workaround manually.
As is, I got an error when trying to create a checkout session that I couldn't define both trial_from_plan and trial_period_days
Even setting trial_from_plan to false didn't work, which still makes sense with the error i got

When deleting trial_from_plan, adding the trial_period_days parameter and changing the code as follows :

if (mode === 'subscription') {
          sessionCreateParams.payment_method_collection =
            payment_method_collection;
          sessionCreateParams.subscription_data = {
            trial_period_days: trial_period_days,
            metadata,
          }; 

I got a working redirection to a stripe checkout page recognizing the 7 day trial period i asked for

Hope this helps
