[bug] duplicated nodes in lockfile cause ERROR: Build-require '...' cannot be found in lockfile

[dornbirndevelops]

Environment details

• Operating System+version: Linux Ubuntu 22.04
• Conan version: 1.57.0

Steps to reproduce

Given a simplified package recipe:

from conans import ConanFile

class Package(ConanFile):
    name = "app"
    version = "1.0.0"

    settings = "os", "compiler", "build_type", "arch"
    
    def build_requirements(self):
        # i want to use something from the grpc package during a cross compile build (which is why this is there) 
        self.tool_requires("grpc/1.45.2@")
    
    def requirements(self):
        self.requires("grpc/1.45.2@")

    def build(self):
        pass

    def package(self):
        pass

I exported the recipe into the cache.

conan export .

I created a lockfile (see lockfile content below -> current version of conan center cannot be used due to conflicts).
The build and host configuration do not matter for now.

conan lock create --reference app/1.0.0@ --lockfile-out conan.lock -b -pr:b default -pr:h default

This yields me this file (recipes are self hosted and slightly patched, hence why revision is not officially available; center-index commit: 10b2fa5).
Notice that protobuf/3.20.0#a67a8047171b10c93a8e69da49dfa79e is entered twice for the "build" context.

yes, good catch @connorsmacd! let's follow the conversation there.
