build error mongoDbFilter.ts

[code-is-art]

I'm trying to build it to test but get this message...

src/mongoDbFilter.ts:108:68 - error TS2345: Argument of type 'GraphQLObjectFilter | GraphQLLeafFilter' is not assignable to parameter of type 'GraphQLObjectFilter'.
Type 'GraphQLLeafFilter' is not assignable to type 'GraphQLObjectFilter'.
Types of property 'opr' are incompatible.
Type 'MongoDbLeafOperators' is not assignable to type '"exists" | "not_exists"'.
Type '"$eq"' is not assignable to type '"exists" | "not_exists"'.

108 const nestedFilter = parseMongoDbFilter(fieldType, fieldFilter, ...excludedFields);

I'm seeing this as well. I'm not sure how the current master branch is building for anyone.
