Problem

I was upgrading an Application from 0.22.x to 1.1.1. While doing so, I was also updating the API to V2 and therefore migrating the GraphQL Queries.

After posting a query to the graphql Endpoint, the request hung up and I checked the logs to find this in the logs:

mesh_1           | Exception in thread "vert.x-eventloop-thread-0" io.reactivex.exceptions.OnErrorNotImplementedException: The exception was not handled due to missing onError handler in the subscribe() method call.

This application contains sensible data, therefore I provide the data privately.
It contains the GraphQL, the original (before 1.1.1 update) graphdb and binaryFiles/uploads data.

Reproducer

Post the appended graphql query within the provided dump as admin.

Expected behaviour and actual behaviour

No errors or a proper Error response which cancels the Request
