Solve the following python programming problem given the following code:
@ defun 
def spherharm(ctx, l, m, theta, phi, **kwargs) : 
    l = ctx.convert (l) 
    m = ctx.convert (m) 
    theta = ctx.convert (theta) 
    phi = ctx.convert (phi) 
    l_isint = ctx.isint (l) 
    l_natural = (l_isint and (l >= 0)) 
    m_isint = ctx.isint (m) 
    if (l_isint and (l < 0) and m_isint) : 
        return ctx.spherharm ((- (l + 1)), kwargs, theta, phi, ** kwargs) 
if ((theta == 0) and m_isint and (m < 0)) : 
        return (ctx.zero * 1j) 
if (l_natural and m_isint) : 
        if (abs (m) > l) : 
            return (ctx.zero * 1j) 
def h(l, m) : 
            absm = abs (m) 
            C = [(- 1), ctx.expj ((m * phi)), (((((2 * l) + 1) * ctx.fac ((l + absm))) / ctx.pi) / ctx.fac ((l - absm))), (ctx.sin (theta) ** 2), ctx.fac (absm), 2] 
            P = [((0.5 * m) * (ctx.sign (m) + 1)), 1, 0.5, (0.5 * absm), (- 1), ((- absm) - 1)] 
            return ((C, P, [], [], [(absm - l), ((l + absm) + 1)], [(absm + 1)], (ctx.sin ((0.5 * theta)) ** 2)),) 
else : 
        def h(l, m) : 
            if (ctx.isnpint (((l - m) + 1)) or ctx.isnpint (((l + m) + 1)) or ctx.isnpint ((1 - m))) : 
                return (([0], [(- 1)], [], [], [], [], 0),) 
(cos, sin) = ctx.cos_sin ((0.5 * theta)) 
            C = [(0.5 * ctx.expj ((m * phi))), (((2 * l) + 1) / ctx.pi), ctx.gamma (((l - m) + 1)), ctx.gamma (((l + m) + 1)), (cos ** 2), (sin ** 2)] 
            P = [1, 0.5, 0.5, (- 0.5), (0.5 * m), ((- 0.5) * m)] 
            return ((C, P, [], [(1 - m)], [(- l), (l + 1)], [(1 - m)], (sin ** 2)),) 
return ctx.hypercomb (h, [l, m], ** kwargs) 

    
    

    Fix the buggy line: return ctx.spherharm ((- (l + 1)), kwargs, theta, phi, ** kwargs)

#Here is Python program to fix the buggy line: return ctx.

return ctx.spherharm ((- (l + 1)), m, theta, phi, ** kwargs)
