Hey 

I am trying to when I click fulfilled order on Shopify a email goes to the customer to say their order is on their way etc. 

I click on flows, select the fulfilment and this error appears. I’ve tried different triggers but the same error appears. I've tried once/ twice a week for weeks now! 

I’ve tried refreshing etc, different browsers, clear cache and different laptops. 

I am on the basic version of Klavijo so I can’t get in touch to log an issue.

Would be great to get the flow set up.
