If you are using offline mode, be aware of gzip compression.
Since it looks like you are using local files, like , then try manually decompressing these pf, json and bin files (you need to add a .gz to the end of the file and then unzip each of them). It will result in bigger files, but you won’t get the warning.
Alternatively, and the recommended approach, is to create a local static server (localhost) that sets the ‘content-type:gzip’ header for the compressed files (PF, BIN and json).
Hope this helps
