Is this in the terminal or in the browser? Can you try to upgrade to Node.js 12 or 14?

Compiles fine in terminal. Fails to load in browser. Will give it a try

Actually the error message seems to indicate that the server returns a "404" when it tries to load libGD.js: WebAssembly/spec#1031

Can you try remove node_modules, and npm install again? Can you check the content of newIDE/app/public, and confirm there is a libGD.js and a libGD.wasm file?

[blurymind]

Tried it and also tried upgrading to node 14, still no luck

Can you paste here the full output of npm install? I'm searching for the lines confirming libGD.wasm was downloaded.
Can you paste here too the content of the newIDE/app/public folder?

Ok I found the issue, fixed in #2448. Sorry for the time loss! You can now pull master and it should work after a npm install.
Don't forget to check all that I'm asking in my messages ("confirm there is a libGD.js and a libGD.wasm file"), that could have speed up the fix ;)

That fixed it, thanks :)
