Switch Pro Controller - Unresponsive joystick after module replacement

After experiencing drift on my Nintendo Switch Pro controllers left joystick and being unable to resolve, I decided to replace the joystick module. After receiving a new one online, I disassembled the controller following iFixit guides. I was able to remove the old joystick module and solder and soldered in the new module. After reassembly, the left joystick doesn't respond at all. I cannot navigate the switch menus or calibrate the control stick through the switch menu. Any suggestions are appreciated!
