Todoist says "Invalid temporary id"

Todoist says "Invalid temporary id"

Hello,

I am testing a Zoho Flow integration between Zoho Projects and Todoist. I am simply trying to create a task in Todoist when a new task is created in Projects. I had some problems converting the date format, but I think I have the proper UTC format that Todoist requires. However, the flow is still failing on this error (see attached screenshots for input and out of the step that is failing):
Todoist says "Invalid temporary id"
Can I get some help troubleshooting this error? Thanks!
