Error: instantiation failed: unknown import, Code: 0x62

[tpmccallum]

I have cloned this React blog software [1] which is also part of a comprehensive YouTube tutorial about React [2].
After building it using the standard npm commands (to make sure it worked) I then went ahead and update the source code and config to be rendered server side. I used the SSR [3] instructions from the WasmEdge book.

Everything was successful right up until the final command to start the server i.e. wasmedge --dir .:. wasmedge_quickjs.wasm ./server-build/index.js

Here is the error which was returned from that command.

maybe you need try linux. sock_setsockopt is unimplemented on mac & windows.

Thanks @L-jasmine
Yes, the server is actually running on Ubuntu Linux.
@hydai asked about the version of WasmEdge; I checked the version on the server and it turns out it was running WasmEdge 0.9.0
I reinstalled using the one-line installer which upgraded WasmEdge to 0.9.1 and the error was resolved, which is great.
Thanks again
