After container build, the Explorer reports that the GraphQL schema cannot be loaded:

{
	"extensions": {
		"debugMessage": "Failed to load type: UpdateFilterInput. Make sure the type is present in your schema definition.",
		"file": "/cdash/vendor/nuwave/lighthouse/src/Schema/TypeRegistry.php",
		"line": 79,
		"trace": [
			{
				"file": "/cdash/vendor/nuwave/lighthouse/src/Schema/TypeRegistry.php",
				"line": 105,
				"call": "Nuwave\\Lighthouse\\Schema\\TypeRegistry::failedToLoadType('UpdateFilterInput')"
			},
			{
				"file": "/cdash/vendor/nuwave/lighthouse/src/Schema/AST/ExecutableTypeNodeConverter.php",
				"line": 37,
				"call": "Nuwave\\Lighthouse\\Schema\\TypeRegistry::get('UpdateFilterInput')"
			},
