As clearly mentioned in the error, the document id is null. Please check your code and make sure the document id will be there.

    Hi, as Deepak said it is very clearly mentioned that the document ID passed is null one more thing here when using these types of components always try to apply to check whether the document passed is not null and the document ID passed is valid.
