[BUG] Error when running model with no existing capacity profile

[sharwaridixit]

Describe the bug

I have a very simple model set up with only one sector with one technology. I seem to be getting the following error message: 'RuntimeError: Subsector with TRA_DMD_PCAR_PET_01 has no output commodities' This error seems to be appearing when the existing capacity file has only 0 values specified for all years of the simulation or 0 in the first year and an existing capacity specified from a later year onwards. If I specify a capacity in the first year or a retirement profile, I don't get any errors. Additionally I don't see the error If I set an arbitrarily small number in the first year. Also, I don't seem to be getting this error when I have a model set up with multiple sectors and technologies.

I am not quite sure what is causing the 'commodities' variable to be empty and have a length = 0 which leads to the error.

The full error message is:

To Reproduce

I have attached the folder with the input files; the existing capacity file currently has a 0 capacity for all the years therefore running the model should show the error. Transport_trial_model_cars_e10.zip
