Graphql plugin doesn't work with apollo schema stitching

[Alfarlost]

I'm using apollo schema stitching and receive next error:

TypeError: Cannot redefine property: _datadog_operation
    at Function.defineProperties (<anonymous>)
    at Object.executeWithTrace (/home/node/node_modules/dd-trace/src/plugins/graphql.js:29:14)

I wonder if just adding writable: true to line 29 defineProperties will be enough.

This means that execute is called multiple times with the same contextValue. To my knowledge this was not possible but maybe schema stitching does that.

I'm not very familiar with schema stitching. Can you share the snippet (or equivalent) resulting in this error?

@rochdev, you can use the full example described in official docs
https://www.apollographql.com/docs/graphql-tools/schema-stitching.html
Just checked, it throws the same error.
Please, use the full example with resolvers between schemas.

Thanks for the reference! I'll take a look.
