Apologies for replying to myself, but I get the same error when trying to use a different caching plugin: netlify-plugin-11ty … So I’m pretty confused.
netlify-plugin-11ty@1.1.0 from netlify.toml and package.json
8:01:11 AM: Uncaught exception, the process will now terminate…
8:01:11 AM: Error: Unable to deserialize cloned data due to invalid or unsupported version
This was after trying to run the build with a cleared cache.
