I think that for virtual machines it has a default value so that it isn't necessary to explicitly provide it. It may not have a default value fro instance types. Can you try adding this to the request to create the instance type? memory_policy=types.MemoryPolicy( max=1 * 2**30 ) Then try again. If it works I think that we need to fix the engine so that it assigns a default value, like it does for virtual machines.
