Try debug(conjugate_gradient(...)), this will spot the line where the error occurs.

Thank you, I made this change and it removed the A/B warning when I try to write it as a CAS program, though I am still getting the Ifte error.

That's precisely why I suggest you to run your program in step by step mode. From CAS commandline, run debug(conjugate_gradient(arguments)) instead of conjugate_gradient(arguments). This way you will know which line of the program raises the error.
