Getting a 500 error when creating a task with PHP

Posted on behalf of Mark Langridge. Original post date 2014-06-30

This is pretty much the same problem as the JAVA one posted earlier. However I am using double quotes, and can't see anything else that could be causing this.

Target Url

https://app.liquidplanner.com/api/workspaces/120300/tasks

Posted String

{"task":{"name":"API Task","parent_id":15821159}}

The cURL trace is

And the response is

stdClass Object
(
    [type] => Error
    [error] => InternalServerError
    [message] => Internal error; try again and perhaps it will work (no promises).
)

anyone spot anything obvious?
