IAP cloud build errors

Hello,
I'm update unity IAP today to the last version, and try to build IOs build, and getting hundreds of errors like:

22: The class UnityChannelPurchaseError could not be loaded, used in Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
23: The class UnityChannelPurchaseError could not be loaded, used in Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
24: The class UnityChannelPurchaseError could not be loaded, used in Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
25: The class UnityChannelPurchaseError could not be loaded, used in Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
26: The class UnityChannelPurchaseError could not be loaded, used in Assembly-CSharp-firstpass, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
27: [Unity] -----CompilerOutput:-stdout--exitcode: 1--compilationhadfailure: True--outfile: Temp/Assembly-CSharp-firstpass.dll

And my build was failed. How can I fix this issue?

 

Does the build work locally? Does the game run in the Editor? If there were any compiler errors during the upgrade, the upgrade may fail. There is more information here:
