Hi,

dot (.) is a string concatenation operation, so line

data=cfunctions.getToken(data);

concatenates value of variable cfunctions (likely null) with returned array, which resulted in a null converted to string concatenated with array converted to string.

Best regards,
Victor

It all makes sense now. So easy when master explains it.

Thank you.

Can you replicate the problem in a simple to use function?

So it sounds like your problem is somewhere else.

Thank you for your reply. You are right. I tried your suggestion of simple function and it worked, so I tracked the problem to calling my function by library_name.function_name(), instead of just function_name().

I don't know if this other syntax of calling ( lib.fn() ) should work or not. I mean, in my code, the correct function was called even with lib.fn() syntax, and it did it's job, just the returning of an array was a problem. (I tested returning just a string and that worked fine).

Do you think this was just mistake in my code and it half-worked by accident, or is this a bug and I should report it somewhere? Anyway, thank you for your help.

Using this in "Execute server script" works fine for example:

sub test() {
  return %(1,2,3);
}

return test()[1];

Moving the function "test()" to a library script named "test_func" and then running this script also works fine:

use test_func;

return test()[1];

So it sounds like your problem is somewhere else.
