The image upload works fine and returns a valid URL ({{guest_photo}})
But the Webhook always returns 400 error, and when I inspect logs, it looks like the variable is not being interpolated ā the final URL ends with just /, not the photo URL.
I suspect this is because I can't use Logic blocks in the free plan, and the variable {{guest_photo}} isn't being resolved in the webhook URL.
My Question: Is there a way to ensure variables like {{guest_photo}} are correctly passed in Webhook block URLs in the free plan, without access to Logic blocks?
Or ā should I upgrade to a paid plan to access Logic blocks for proper interpolation?
