Crashing when trying to save (Trigger=Webhook)

Crashing when trying to save (Trigger=Webhook)

Hey all!

Scenario: 

Created a flow triggered by a webhook that is attached to a button on my zoho crm leads module in order to create a module entry on zoho crm and fetch details from leads module.

Problem: 

1. Tested connection succesfully and received complete payload
2. Created flow and assigned payload which was correctly mapped
3. Click on SAVE BUTTON: CRASHES
4. Click on TEST AND DEBUG: CRASHES

This only happens when trigger is a webhook.
