# Since we serialize the build output ourselves to ensure Gitaly
# gRPC calls succeed, we need a custom Grape format to handle
# this:
# 1. Grape will ordinarily call `JSON.dump` when Content-Type is set
# to application/json. To avoid this, we need to define a custom type in
# `content_type` and a custom formatter to go with it.
# 2. Grape will parse the request input with the parser defined for
# `content_type`. If no such parser exists, it will be treated as text. We
# reuse the existing JSON parser to preserve the previous behavior.
