[Fix in 2020.1.a17] v0.4.0: ContentBuildInterface missing GetPlayerObjectIdentifiersInSerializedFile

Hi all,

I've moved to entities 0.4.0-preview.10, but am sadly getting the above error(s):
* Library/PackageCache/com.unity.entities@0.4.0-preview.10/Unity.Scenes.Editor/LiveLink/LiveLinkBuildPipeline.cs(257,61): error CS0117: 'ContentBuildInterface' does not contain a definition for 'GetPlayerObjectIdentifiersInSerializedFile'
* Library/PackageCache/com.unity.entities@0.4.0-preview.10/Unity.Scenes.Editor/LiveLink/LiveLinkBuildPipeline.cs(323,37): error CS1579: foreach statement cannot operate on variables of type '?' because '?' does not contain a public instance definition for 'GetEnumerator'

This is my manifest:

I don't appear to be the only one. Looking at the code, I believe this may only be occurring for Unity 2020.1+ (I am using 2020.1.0a16.1913).

Is my assumption correct that it's only for 2020.1 users?

Cheers

 

I'm not getting this error, and I'm using 2019.3.0f1

 

a temporary solution is open the file where the error is coming and change

to

 

Thank you very much for your answers, much appreciated!
