how about making the API file like this?

```
STRUCT ARRAY123
{
string Array1[10];
int32 port1;
string Array2[10];
int32 port2;
string Array3[10];
int32 port3;
string Array4[10];
int32 port4;
string Array5[10];
int32 port5;
};

FUNCTION arraySend
(
ARRAY123 asd IN
);

```

It is working on my side with vscode leaf swi-wp76\_4.7.0.  
You can use my code:
