DevOps "Update a Work Item" task error message; invalid inputs

[tonybox]

When using the Update a Work Item Azure DevOps task, I get the following API error when trying to save my Flow:

Flow save failed with code 'DynamicParameterInputInvalid' and message 'The request to API 'visualstudioteamservices' operation 'GetWorkItemSchemaForUpdate' has invalid inputs. Error details: The API operation 'GetWorkItemSchemaForUpdate' is missing required property 'typeName'.'.

I've tried filling out all of the fields, only the minimum fields, dynamic/not-dynamic content... everything I can think of but I can't get this task to work. It seems like something on the back-end of the task is missing a required json property. Maybe the back-end API was updated and this task was not?

I suppose to update Work Item Type is not work currently.

I have tried to update description and Work Item Type, but only Work Item Type is not updated.
