Trying to deploy types and it says now that relations need to be in format of

MyType

,

MyType!

, or

[MyType!]!

whereas

[MyType!]

was allowed before. Does this now mean there must always be objects within this because of the array being required?

It has always been [MyType!]!, even for optional relationships. An empty array satisfies this condition, so that means that relationships are still optional.

It was totally deployed with

[MyType!]

but good to know and it must have been corrected now. Thanks!

@zebapy it was deployed as

[MyType!]

before, but it would actually be "interpreted" as

[MyType!]!
