How can I update the code of a docker image??

To update the code of a Docker image, you generally have a couple of options depending on how the Docker image was built and how it's managed.

note that if you're using a Docker image from Docker Hub directly and don't have access to the Dockerfile or source code used to build it, you won't be able to directly update the code within that image. In this case, you'll need to wait for the maintainers of the image to release a new version with the bug fixes applied. Alternatively, you could consider creating your own Docker image based on the existing one.
