I have a project with two tasks on it. Both tasks are active. I am using REST API to mark the task as complete. I keep getting an error that says “The Complete Button is disabled”
This message is misleading as the button is very much enabled on the UI.
Please see screenshots.

How do I mark a project task as COMPLETE?

Not sure if you figured this out, but I had the Same issue. In the Payload it is not “TaskID” It is "ProjectTaskID” Once I changed that all is working.
