GCBM Test suite does not report simulation failure

[Namyalg]

Currently, when the GCBM example simulation is run locally, fails. However then test suite for does not report a failure.
The behaviour observed is as follows :

1. /gcbm/new and /gcbm/upload function as expected in the test suite and locally
2. On running /gcbm/dynamic locally, the endpoint returns (200, {"Run started"}). Soon after the simulation fails. This is not covered in the test suite.
3. On a failed simulation, an output folder is created, however it is empty
