Oddly enough, I can no longer reproduce this issue.

Sorry for the noise on this issue, but I just realized what I had done which apparently got around this issue.

I fixed a new warning in my web server library

warning: opaque type impl warp::Filter + Clone + warp::filter::FilterBase<Extract = impl Reply, Error = Rejection> does not satisfy its associated type bounds

by turning this..
pub fn make_graphql_filter(schema: crate::graphql::Schema) -> impl Filter<Extract = impl warp::Reply, Error = warp::Rejection> + Clone

into this

pub fn make_graphql_filter(schema: crate::graphql::Schema) -> impl Filter<Extract = (impl warp::Reply,), Error = warp::Rejection> + Clone

I caused this. Let me put up a fix.
