What happened?
Hi,
when trying to compose 2 subgraphs:
subgraph #1
type Mutation {
impersonate(...): Mutation
}
subgraph #2
type Book {
id: ID!
}
type Mutation {
upsertBook(..): Book
}
The composition fails complaining that we should either transform the Mutation type to an Entity with an @key field or declaring @Shareable impersonate in the 2 subgraphs (we can't do this)
I assume that it is a issue related to Root types, the composition succeeds in Apollo graph os
