Python API does not work with 23.08

[ArmiSchm]

I have observed two issue:

• A python-script, was running perfectly with a simba-project modified and stored in 23.05
• I have loaded this project into 23.08 and saved it.
• When I start the python-script observe two different types of errors:
  1. project is loaded, but the Designs cannot been found with "GetDesignByName" (Hint: I've looked into the project data structure and see, that a) not all designs are imported. b) the Designname is not imported)
  2. project cannot loaded. I'm receiving a JsonException: The JSON value could not be converted to System.Double. Path: $.Designs[0].TransientAnalysis.EndTime | LineNumber: 2077 | BytePositionInLine: 25. ---> System.InvalidOperationException: Cannot get the value of a token type 'String' as a number. at System.Text.Json.ThrowHelper.ThrowInvalidOperationException_ExpectedNumber(JsonTokenType tokenType) at System.Text.Json.Utf8JsonReader.TryGetDouble(Double& value) at System.Text.Json.Utf8JsonReader.GetDouble() at System.Text.Json.Serialization.JsonConverter1.TryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, T& value) at System.Text.Json.Serialization.Metadata.JsonPropertyInfo1.ReadJsonAndSetMember(Object obj, ReadStack& state, Utf8JsonReader& reader) at System.Text.Json.Serialization.Converters.ObjectDefaultConverter1.OnTryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, T& value) at System.Text.Json.Serialization.JsonConverter1.TryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, T& value) at System.Text.Json.Serialization.Metadata.JsonPropertyInfo1.ReadJsonAndSetMember(Object obj, ReadStack& state, Utf8JsonReader& reader) at System.Text.Json.Serialization.Converters.ObjectDefaultConverter1.OnTryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, T& value) at System.Text.Json.Serialization.JsonConverter1.TryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, T& value) at System.Text.Json.Serialization.JsonCollectionConverter2.OnTryRead(Utf8JsonReader& reader, Type typeToConvert, JsonSerializerOptions options, ReadStack& state, TCollection& value)

@ArmiSchm , thanks for the issue. We will look into it right away. Can you please confirm which version of the python module are you using (pip show aesim.simba)?

@AdriPWS, are you able to reproduce this issue ? If yes, can you please share a project file for 23.05 and a script causing those exceptions ? Thanks.

Hi, Please could you give me the version of the python module that you are using as asked by Emmanuel? In command prompt, just type : pip show aesim.simba

Then I tried to reproduce your issue but I failed (sorry for that):

I downloaded SIMBA.exe version 23.5.5.0 and did a simple buck converter + saved the project (.jsimba file) I downloaded aesim.simba version 2023.5.19 and run this simple buck converter in python and it worked well.

Now I downloaded aesim.simba version 2023.8.1a1 and launched the same script and it worked as well Now I downloaded aesim.simba version 2023.8.31 and launched the same script and it worked as well

So I also loaded the .jsimba project created earlier into SIMBA.exe 23.08.31 and launched the same script as before with still aesim.simba version 2023.8.31 and it worked again.

Sorry I don't succeed to reproduce your behavior. Did you think to update the python version? pip install aesim.simba==2023.9.25a1 Can you try also please? We can set up a meeting as well.

Thanks, Adrien

Hi, I just updated to pip install aesim.simba==2023.9.25a1 and the error did not occur. THX

[AdriPWS]

Hi, Ok perfect, thanks for your positive feedback. So everything is solved now.

[ArmiSchm]

Yes. Perfect. I suggest to add some kind of revision check between the Simba.exe and the API.

You can now close the topic. THX.

[AdriPWS]

I totally agree with you and we already do that but I have tried to reproduce your issue without success. I used 2023.9.25a1, 2023.8.31 and 2023.5.19 and even with those version I don't have your error message. So I don't understand what's happened.

As your problem is fixed, yes we can close. But for sure we will double check that for later revision.

Thanks,
