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?
When the task initially ran the following error showed up:
Error Message: Error returned from server:
soaperverServer was unable to process request. ---> Cannot get the full
name or e-mail address of user "John Doe". ---> Exception of
type 'System.ArgumentException' was thrown.
Parameter name: value
John Doe is the user who the task was originally assigned to.
