Expression Evaluation Error

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.

I'm a beginner can you please tell me how to resolve this error . I have created a Supervisor Form everything is working fine . But when I am trying to approve this form in process model it is showing this error.

Can you please share the code snippet and process variables screenshot the id which you are passing to the image filed is not valid or null.
