tried to redefine existing error around graphql

Question

I have 2 project(graphql client) with schema.graphqls each fro different graphql endpoints, and have some same definitions.

Project A --schema.graphqls --type Order... type Product... Project B --schema.graphqls --type order... type Product...

The project A and B managed by a parent project like below

<modules>
    <module>../projectA</module>
    <module>../proejctB</module>

So, when I run one of the 2 project will throw the error below

There are problems with the GraphQL Schema:
     * 'Mutation' type [@307:1] tried to redefine existing 'Mutation' type [@10:1]
     * 'Order' type [@374:1] tried to redefine existing 'Order' type [@455:1]
     * 'OrderConnection' type [@421:1] tried to redefine existing 'OrderConnection' type [@439:1]
     * 'OrderEdge' type [@429:1] tried to redefine existing 'OrderEdge' type [@447:1]
     * 'PaymentMethod' type [@502:1] tried to redefine existing 'PaymentMethod' type [@501:1]
     * 'Product' type [@518:1] tried to redefine existing 'Product' type [@571:1]

How can I resolve the issue? Thanks a lot!
