NullPoint Exception from cosimulation scenario #406

Open clagms opened 1 year ago

clagms commented 1 year ago

The following scenario results in null pointer exception and I was not able to assess the cause.

scenario_null_point_exception.zip

To reproduce:

  1. Get maestro jar with dependencies into the local_cosim folder.
  2. Cd into folder
  3. Run java -jar maestro.jar sigver generate-algorithm scenario.conf -output results --> Should be ok and generate
  4. Run java -jar maestro.jar sigver execute-algorithm -mm multiModel.json -ep executionParameters.json -al results/masterModel.conf -output results -di -vim FMI2
  5. Get the error below.

The problem here might be between the chair and the screen, but at least we ought to produce a nice error message to help the user figure out what it is.

PS C:\work\gitlab\project_digit-bench-dlte\claudio\distributed_model_tunning_example\decoupled_model_cosim\maestro_cli\local_cosim> java -jar maestro.jar sigver execute-algorithm -mm multiModel.json -ep executionParameters.json -al results/masterModel.conf -output results -di -vim FMI2
