I had a running GETH node linked to my localhost (hosted with Apache) , I had to migrate the project on a ExpressJs running on port 3000 and now I have

Error: CONNECTION ERROR: Couldn't connect to node http://localhost:8545

When I run the exact same code with the same GETH instance (but with Xampp) , everything works fine.

Any clue ? Thanks all

EDIT :

Apparently , it's maybe because NodeJS doesn't have the writing permission. Does anyone knows how to allow it on Linux ? Thanks
