When following the code in the “CRUD Operations Using Mongoose: saving a document” part:
if I follow the course code and mongoose version, it gives me error:
MongoError: Unsupported OP_QUERY command: insert. The client driver may require an upgrade. For more details see https://dochub.mongodb.org/core/legacy-opcode-removal

code: 352,
codeName: 'UnsupportedOpQueryCommand'
}
If I upgrade the driver to current, error message become
(node:6408) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.
(Use `node --trace-deprecation ...` to show where the warning was created)
(node:6408) [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
So I changed the code to
mongoose.connect('mongodb://localhost:27017/playground', { useNewUrlParser: true, useUnifiedTopology: true })
Now it just doesn’t respond and eventually timeout.
What’s the problem here? Any help is appreciated!
My OS is Win10, vs code version 1.74.2, Node version 16.14.2
