Hi! I'm sorry to hear you're experiencing this issue.
This might be happening because if the parameter is defined as an integer, it's expecting an integer value — but instead, you're passing a "-", which could be causing the error.
Unfortunately, the project you sent appears to be empty, so I wasn't able to review it.
Best regards.

@Juansarmi
Naturally, it expects a valuable number, but you can also enter the "-" sign in the field. Please note that other symbols or letters cannot be entered - after all, it is logical. Please pass it on for correction and remove the ability to enter this symbol.

I have no information why project is not visible for you - it exists and works.
I will repeat the code, from a more understandable place.

Hi again,
If you'd like to return a string data type, you can change the data type of your parameter accordingly.
That said, I completely understand your point, and I’ll bring this up with the team for further discussion.
Best regards.

[stasik0808]

The problem is not that you want to output. If for some reason, this symbol is entered - by mistake it will not even be clear what and where to look for. And this is possible if you change the parameter from string to int and do not pay attention to the standard parameter.

Hi again!
I understand your point.
I'll share your case with the engineering team to see if this is something they might consider as a potential improvement to the platform.
If that's the case, I'll make sure to keep you updated.

Thanks so much for your input!
Best regards
