Batching operations (array) returns BadRequestError
When using an array inside the operations field, I always get this error:
BadRequestError: Invalid type for the ‘operations’ multipart field

I used the example query from here https://github.com/jaydenseric/graphql-multipart-request-spec#curl-request-2

When using a single object instead of an array, it works.

Looking into the source code, I found the check isObject(operations). This seems to return false for arrays. Please also allow arrays in that type check!
