Can't pass char* from JS to cpp function

I get this error regarding 'fromWireType':

When I try to call this function:

  `
  static char * createShares(char *data, int n, int t) {

    seed_random();

    std::cout << "String: " << data << "\n";

    char * shares = generate_share_strings(data, n, t);

    return shares;

    }`

Moreover, when I try to print the data var, it doesn't show anything in the console.

I mention that _generate_sharestrings is a function taken from this secret sharing library:
