I created a new Workflow only compose by a flexy task.
When I answer it (independentof the answer choice), I receive the error :
The value cannot be null. Parameter name : String
I have no parameters in my Workflow.
I tried with the request approval and I encountered the same problem
Have you any ideas where this error come from ?
Thank you in advance
I created a new task list in the workflow setting and let the form type to default
So I think it use the default SharePoint one
I found the solution. It was just because I used the farm account to answer the flexi task.
When I assign the task to a standard user, I haven't the error
Thank's for you help
