MadAnalysis5 failed to write a parton-level default analysis card for this process.

Question

Dear MA5 experts:
Sorry! When I run a self-created U(1)-extended Standard Model with four CP-even and CP-odd Higgs particles and three charged Higgs particles, the desired processes are generated successfully. However, an error occurs when generating MadAnalysis5 default cards tailored to this process.

WARNING: MadAnalysis5 failed to write a parton-level default analysis card for this process.
WARNING: Therefore, parton-level default analysis with MadAnalysis5 will be empty.
WARNING: MadAnalysis5 failed to write a hadron-level default analysis card for this process.
WARNING: Therefore, hadron-level default analysis with MadAnalysis5 will be empty.

I cannot find any hints indicating the source of the error. Are there any methods to help me locate the issue?
The built-in models do not encounter this issue. Alternatively, what key aspects should be considered when creating a custom model? The version of mg5amcnlo is 3.6.2 and MadAnalysis5 is 1.9.60。

I asked the author of MG5, and he suggested that I come to ask for your help.

Hi, This is not an error but a warning. So in principle this is not a big problem and you could edit the MA5 card on runtime to plot whatever you want. Note that I cannot acess your github folder, and that I would need the proc_card in addition to reproduce and understand what is going on. Cheers, Benjamin PS: I won’t be able to follow up on this for one month as I will be leaving for vacation very soon. Sorry in advance.

Thank you for your enthusiastic help, and I apologize for interrupting your vacation. Below is my proc_card.dat. Wishing you a wonderful holiday! Sorry, git@github.com:CC-czz/demo1.git is now visible. I have changed the repository visibility.
