PUT method to update a task returns "Unknown object" error

Below is my httр request and asana’s response.
I can read a Task with GET, I am able to create a Task with POST,
However PUT returns me the error, although I do the PUT request as it described in API Reference.
What might be wrong?

The syntax looks right, offhand.

Where did you get that Task ID from? Are you 100% sure a task with that ID exists? Also, is it possible that the API key you’re using does not have access to that task? That would also lead to an “unknown object” error, I think.


Phil, yes you are right!
My silly mistake, I used different tokens for read and update, and the second token had no access to the Task.
The problem is solved.
