You’ve created the model with the same name in ./plugins/auth-wechat-minprogram, which is wrong.
You should use extensions if you want to modify some the plugin’s files.
- Create the file in:
./extensions/users-permissions/models/User.settings.json, - Copy the content from
./node_modules/strapi-plugin-users-permissions/models/User.settings.jsonto the newly created file - Now you can modify the file in
./extensions/users-permissions/models/User.settings.jsonand add new fields.
