@Mohammed-Abdel-Aziz Have you configured the plugin_opt_config_file?

plugin_opt_config_file /tmp/security_dynamic.json

and make sure the file /tmp/security_dynamic.json exists

The error message "File is not readable" is misleading, you would get the same msg if the file is not found at all. Check the name, path etc. I had the same issue and it turned out that I had a syntax error in the .json file name... :)
