Todoist to To-Do: Completing tasks fails with "Invalid temporary id" error

I created a Zap for: create new task in Todoist → creates new task in Microsoft To-Do. 

But, I can’t seem to get this to work:  Complete task in Microsoft To-Do → completes same task in Todoist. 

I get this error: {"message":"Task Completion failed: Invalid temporary id"} 

What am I doing wrong?

Hi there @Nick S,

Welcome to the Community! 🎉

Before we dig deeper into this, would you mind sharing a detailed screenshot of how your Zap is configured? Could you also please send a screenshot of the “Action” section of your action step that shows all of its fields? Here’s an example screenshot:

Please don't include personal information in the screenshot, or be sure blur out any personal information.

Hi @ken.a 

Thank you. 

Apologies for the vague post 😅.

Think I’ve found the answer to my question: “Complete task in Microsoft To-Do → completes same task in Todoist”.

The zap needs a step in the middle to search for the task in Todoist, therefore, a multi-step zap!  Which is not available with the free plan. 

It would be great if Zapier introduced a baby tier for pricing i.e., 5 bucks per month for a few multi-step zaps. Hard to justify $20 per month to automate just one or two things.
