When syncing an epic issue from next-gen project to classic project, an error triggered.

```auto
ErrorCollectionValue(List(),List(FieldErrorValue(customfield_10005,Epic Name is required.)))

```

What I did to tackle it is adding the following code in the incoming sync rue of destination side.

```auto
if(issue.typeName == "Epic"){
   issue.customFields."Epic Name"?.value = replica.summary
}

```

May you advise my solution and I would like to look for a better one if available.

Hi Cloud Chiu

This is also how we would do it.  
The error indicates that the epic name is not set, and by adding the snippet, it is.
