ServerError(500) when two inputs provided to components which only allow only one

[JPelda]

After first simulation with failure message, I changed the model slightly.
Now I receive "Server Error (500)" when I start Simulation or like to export the model as .json.

Hello @JPelda - Thanks for submitting an Issue. In order to better help you it, it would be useful to have your Scenario's number, you can find it within the URL : https://open-plan-tool.org/en/project/<your project number>/scenario/create_parameters/<your scenario's number>. If you do not want to share it openly on github, please share it with us via the feedback form:

@JPelda - Alternatively, you can also describe which parameter from which asset you changed and the name of the orginal model you used, maybe this will be enough for us to help you

Dear Bachibouzouk,

this ist the scenario I am talking about: https://open-plan-tool.org/de/project/3217/scenario/create_parameters/11547

Best regards

Hello @JPelda I had time to look at your problem

The problem arised from the heat pump 2

Both bus 6 and bus 8 are connected to the heat pump and it is not (at least currently) allowed. You should do something like this:

With the values of the transformer being the following:

In order to make the system actualise your design I would recommend to delete the connection between bus 6 and the heat pump 2, then save, then introduce the transformer and connect it, then save again, then you should be good to go :)

I apologize for the disagreement! Thanks to your bug report we get a chance to improve the user experience.

@paulapreuss, @josihoppe @CelinaKellinghaus - I think we should give the user a fairer warning in such a case

Dear Bachibouzouk,
Thank you for your reply and the excellent description.

Unfortunately, the new system design still throws an ERROR: "Server Error (500)".

I changed the connections to the grid according your explanation. I also tried another project where I added grid connection. It is project: https://open-plan-tool.org/de/project/3113/scenario/create_parameters/11189

I changed also the system design of the other project to the following:

@JPelda - When looking for the error and trying to fix it I experienced that one needed to actively click "save" after one deleted the link (select them by clicking on them and hit the "del" keystroke). I suggest you submit a feedback via the "About us" menu in the navigation bar and select "Feedback". This way I will be able to share my email address with you so that you can share your project with me (with edit right) and I can make sure you scenario works for you.

The two designs I see both have the problem that the heat pump receives two electrical inputs (two yellow lines come into the dot) and this is not allowed.
