[Bug]: IllegalArgumentException when Building the GraphQL Package

[ThisaruGuruge]

Description

We have recently introduced the parallel execution support for GraphQL. This change was done on Ballerina 2201.9.x. However, when we try to port those changes to the 2201.10.x and master branches, we observe the following error:

Compiling source
        ballerina/graphql:1.15.0
ballerina: Oh no, something really went wrong. Bad. Sad.

We appreciate it if you can report the code that broke Ballerina in
https://github.com/ballerina-platform/ballerina-lang/issues with the
log you get below and your sample code.

We thank you for helping make us better.
