Description
We are newly hitting this with Juniper across all channels and platforms. While there are other issues with similar errors, they either say it only happens with nightly or requires GATs, neither of which are in use here.
error: internal compiler error: src/librustc/traits/codegen/mod.rs:53: Encountered error `Unimplemented` selecting `Binder(<&dyn tests::model::Human as types::async_await::GraphQLTypeAsync<value::scalar::DefaultScalarValue>>)` during codegen
