Authorize query null for persisted query

Hi ! I want to use persisted query.

To respect apollo persited query protocol
(https://www.apollographql.com/docs/react/api/link/persisted-queries/#protocol).

I will send one request where my query is not defined.
But ExecutionInput builder don't support null query.

this.query = assertNotNull(query, () -> "query can't be null");

In graphql kickstart spring boot lib
One exception is return when GraphQLSingleInvocationInput.createExecutionInput() is executed.
I see in this MR your raise a question but I don't find a solution.

Is it posibel to overide the ExecutionInput build rule ?
