Email Reader Snap issue while storing attachments

Hi,

I am able to fetch the attachments using email reader snap but when I try to store the attachments into a project specific path or within the pipeline I am getting the below error:

Failed to retrieve messages

Resolution:
Please address reported issue.

Reason:
Failed to get file attributes for //HPE-dev/projects/attachments/Inte_certificate.pdf

N.B: I am able to successfully save the attachments to shared folder but unable to store it else where.
