How to pass DataSources to Context? about aws-lambda-graphql

[ffleandro]

It seems that this is not being bound correctly inside the DataSource.
One of the DataSources is a DynamoDBDataSource and some methods work and other don't.

For instance, deleteItem throws:
Cannot read property 'removeItemFromCache' of undefined

and getItem throws:
Cannot read property 'getItem' of undefined

But put or update work fine.
I have a similar error using a RESTDataSource.

It seems the problem is when instantiating the datasources, because previously using apollo-server-lambda I pass a method that will instantiate the DataSources and it's going to be called for each operation, according to the apollo-server docs: https://www.apollographql.com/docs/apollo-server/data/data-sources/#adding-data-sources-to-apollo-server

Fixed like this:

const serverConfig = {
    dataSources
};

const server = new Server({
    ...serverConfig,
    connectionManager,
    eventProcessor,
    resolvers,
    subscriptionManager,
    typeDefs,
});
