Updated Plugins fails to recognize the datapck structure?

[R1yan1]

I met a bizzare situation that when I update this plugin to 2.1.12 version, it fails to recognize my datapack structure and keeps poping "The datapack's pack_format may be incorrect." when I try to "copy resource path" of a file in my datapack. While when I rollback the plugin to the 2.1.11 version, the "copy resource path" function works normally. I am not sure where is going wrong, but my datapack structure is always recognizable for 2.1.11 version as I have tested with several times of uninstallation. I guess you have been changes with some code of recognization? I have limited understanding of Javascript, so I cannot actually figure out the code that contribute to this problem, sorry for that. Plus, a new datapack created by the plugin template is also unrecognizeable when it comes to "copy resource path" function.
