It seems like a permission issue. Can you check on the server user for running wso2 service has read/write permissions for artifact location? You can get the server user for wso2 server by command: ps -ef|grep wso2. Then you can check the permission for the artifact location by executing the following command.
ls -lrt repository/deployment/server/synapse-configs/default/
If the server user doesn't have write permission for the artifact location you need to provide the ownership to the user for the artifact location[1]
