Missing files when try to update V8 and Hermes

Hello, I'm trying to update my engines via jsvu. The engines Chakra, SpiderMonkey and JavaScriptCore works as expected, but V8 throws a Promisse error when try to rename a file that does not exists. The zip file extracted does not contains the natives_blob.bin, only the snapshot_blob.bin and icudtl.dat.

✔ Found latest V8 version: v8.5.74.
✔ URL: https://storage.googleapis.com/chromium-v8/official/canary/v8-linux64-rel-8.5.74.zip
✔ Download completed.

I tried to install Hermes too and another error was thrown.
