Problems deploying wordpress in updated elsatic beanstalk environment

Question

I wanted to update my environment to one that has php version 8. I configured it with the same variables as the environment I have running with php 7.2, and I deployed it with the example application that comes in elastic beanstalk.. the environment status is OKAY. When I want to deploy wordpress, it throws me an error when trying to create the symbolic link in /wp-content/uploads (since I have efs/uploads).

This is the cfn-init.log:

the efs.config file is the same one I use to deploy the changes in my production environment and I have no problems, but in this new one with version 8 of php I do have
