I'm seeing random NonNullableValueCoercedAsNullExceptions from our servers running graphql-java 17.3 with graphql-java-tools 12.0.2. I've logged the entire GraphQL query, variables, and operation name, and I cannot reproduce the exception. The stack trace looks like this:
graphql.execution.NonNullableValueCoercedAsNullException: Field '' has coerced Null value for NonNull type 'String!'

Can someone please give me some general directions on what the error means?
I know if I put a null inside an array that requires non null values in variables, I can cause an error with the same error message. However, if you look at the stack trace, the exception was thrown at graphql.GraphQL.executeAsync, meaning I'm not even getting a result from it.
Also for the record, this is what my variables looks like:
{
"accountId": "133...63",
"userId": "133...63",
"userInput": {
"accountId": "133...63",
"id": "133...63"
}
}I do not have arrays or nulls in my variables.
