classify email AI - error :The user does not have permission to view document

Hi,

overview :

1. I am sending a email to process model and store the data's in pv

2. With the use of (Create Eml File from OOTB Poller) smart service generating a document in EML format

3. In classify email AI - passing the generated document as input.

I am getting an error saying " The user does not have permission to view document " in classify email

All objects(AI,process model,document folder) have Admin access

Also the generated doc from step 2 is showing "not in the application" but it is in document folder within the application

Pla suggest a solution to resolve this.

Thanks in Advance
