1. Error in importing configuration file using Nacos: no legal data is read, please check the imported data file

compared with the files exported in the naocs server, it is found that there is a level 1 directory missing. You need to create a folder with the name of the group
because the namespace can be selected when Nacos uploads files, but the group will not be selected, the Nacos server identifies and reports an error

2. Create a folder named default_Group, then put the configuration file in, package and upload successfully
