module 'dash_uploader' has no attribute 'UploadStatus'

The callback function.

@du.callback(
    output= Output("analyze-val", "disabled"),
    id= "dash-uploader",
)
def callback_on_completion(status: du.UploadStatus):
        return False

Error:

def callback_on_completion(status: du.UploadStatus):
AttributeError: module 'dash_uploader' has no attribute 'UploadStatus'

I am new to DU and Plotly dash development in general, have I missed something? This is error is quite unexpected as there's not much that could go wrong with this basic code. Any suggestions? Thank you in advance.
