We have a task delegation workflow which permits users to delegate tasks to another user on the system. The workflow assigns the task to another user but when the user tries toopen the task they get the following error
Authorization error while loading custom task response form: You are not authorized to respond to this task
I have attached a ULS entry for a single such task. The user got this error when trying to open a task that was delegated to them.
Any ideas why this might happen?
