As the title, I try to solve an ODE:

y(x) = (x - 1)*(x - 3)*diff(y(x), x) + f((x*y(x)^2 - 4*x*y(x) + 3*x - y(x)^2 + 4*y(x) - 1)/(x - 3))
And it seems that the ODE can be solved using Lie Symmetry method. But as I choose f to be a simple exponential function, dsolve fails to give the solution. I also try the DEtools[symgen] and receive the same result.

Can anyone tell me what's the problem? Is there some internal bug?
