Virtual Entities - 1:N Relationship

Hi Everyone,

I have two virtual entities in my Solution named as 

• Project
• Issue

Data source is an Odata V4 API I built to retrieve Projects and Issues from JIRA. The issue is I want to have a 1:N relationship between Project and Issue as they are in JIRA. I am trying to add a lookup field of"Project" on my issue entity providing the field having guid of project (projectid) as external name. I save and publish the entity but when I try to access related Issues through Project or Advanced Find I get error as below:

If I remove the lookup field, I can access them but I need to show them as related i.e. one project has many issues.

Below is how I created a Lookup field on "N" side of record i.e. Issue

Below is my Odata API Meta Data showing both records metadata.

Any suggestions would be greatly appreciated. Thanks in Advance.
