   I found that it is because of global header_filter does not generate `conf_id`, in https://github.com/apache/apisix/blob/master/apisix/init.lua#L555
   ```
       if api_ctx.global_rules then
           local plugins = core.tablepool.fetch("plugins", 32, 0)
           local values = api_ctx.global_rules.values
           for _, global_rule in config_util.iterate_values(values) do
               // here should generate global rule's id and type like L312
               core.table.clear(plugins)
               plugins = plugin.filter(global_rule, plugins)
               run_plugin(phase_name, plugins, api_ctx)
           end
   ```
   
   I will fix it tonight.
