graphql-executor's Issues

Variable \"$value\" expected value of type \"UniqueEnum\" which cannot be used as an input type

Hi, I'm getting such an error if using a non-nullable arg of type Enum with a default value and corresponding nullable variable in case there is no nullable arg of the same type in the schema.

It looks like _toExecutorSchema adds the non-nullable version of the enum to the inputTypes Set and to the typeTree. Then coerceVariableValues tries to get a nullable version of the enum (because of nullable variable) from the inputTypes Set and from the typeTree. It cannot do that because there is the only non-nullable version of the enum.

v14 support

isSubType was introduced in v15 ?

We could introduce our own startup processing of the schema on first execution, memoizing the result.

There may be other blockers as well.
