My code doesn't work, can I have yours?

Hello,
I am currently trying to implement Hand-eye calibration for an XArm vArm6 robot arm equipped with an Intel Realsense D435 camera. I am currently facing errors in the conversion from pose vector to rotation matrix using the Rodrigues function in OpenCV. Do you have any tips on how to get consistent results? Also is it possible for you to share your entire code, it would be really helpful.
Thanks

please show, what you’re doing there (data,code), and highlight, where it fails, no ?
