Property 'originalError' in type 'ApolloError' is not assignable to the same property in base type 'GraphQLError'.

Before going into more detail here:

I am receiving now the error that there is a mismatch between two types:

Namely, in node_modules/apollo-server-errors/dist/index.d.ts:10:5 Apollo Error implements GraphQLError.

export declare class ApolloError extends Error implements GraphQLError {
    extensions: Record<string, any>;
    readonly name: string;
    readonly locations: ReadonlyArray<SourceLocation> | undefined;
    readonly path: ReadonlyArray<string | number> | undefined;
    readonly source: Source | undefined;
    readonly positions: ReadonlyArray<number> | undefined;
    readonly nodes: ReadonlyArray<ASTNode> | undefined;
    originalError: Error | null | undefined;
    [key: string]: any;
    constructor(message: string, code?: string, extensions?: Record<string, any>);
}

whereas GraphQL Error is defined as such:

export class GraphQLError extends Error {
  constructor(
    message: string,
    nodes?: Maybe<ReadonlyArray<ASTNode> | ASTNode>,
    source?: Maybe<Source>,
    positions?: Maybe<ReadonlyArray<number>>,
    path?: Maybe<ReadonlyArray<string | number>>,
    originalError?: Maybe<Error>,
    extensions?: Maybe<GraphQLErrorExtensions>,
  );
...

As of now, we cannot proceed with using our Backend, also downgrading to what it previously was seems not to be the solution.

Please fix this asap. Thank you very much.
I'll open a pull request for this as well.

@woltob Thanks for reporting fixed in https://github.com/graphql/graphql-js/releases/tag/v15.7.1

FYI: This problem also effects graphql 16.x. I've already notified IvanGoncharov in that repo's ticket.
