Truffle v5.5.1 (core: 5.5.1)
This is my truffle-config.js
matic: {
provider: () => new HDWalletProvider(mnemonic, `https://polygon-mainnet.g.alchemy.com/v2/key`),

},
Does anyone know why is this happening?

Make sure that you have globally installed MySQL2 using this command:
npm i -g mysql2
If the problem persists, try downgrading node version to 10.

I try to connect to mongoDB through docker-compose but i get the same error over and over again although i tried all the solutions from the net. Thank you.
I have my docker-compose.yml as
# Use root/example as user/password credentials

mongo:
image: mongo

container_name: mongo

ports:

environment:

And I have such a shell script
mongo -- "$MONGO_INITDB_DATABASE" <<EOF
db.createUser({
user: "$MONGO_USERNAME",
pwd: "$MONGO_PASSWORD",
roles: [
{ role: 'readWrite', db: "$MONGO_INITDB_DATABASE" }
]
})
EOF
And I try to connect to database by:
mongoose
.connect("mongodb://admin:example#localhost:27017/test")
.then(() => console.log("connected"))
.catch((e) => console.log("error:", e));
In Linux my friend can connect with the same code pieces but I am getting this error :

I solved this just by changing the port from 27017 to 27018. Unfortunately, another app of mine was using that port.
There is my solved used :
docker-compose -f stack.yml up --build --force-recreate --renew-anon-volumes -d
stack.yml :
version: "3.5"
services:
mongo:
image: mongo:latest
container_name: mongo

Replace path with your compute absolute path.
And DO NOT use 'root' to authentication.
use mongosh
shell script can use:
mongosh --port 27017 --authenticationDatabase -u "$MONGO_INITDB_ROOT_USERNAME" -p "$MONGO_INITDB_ROOT_PASSWORD" <<EOF
use admin
db.createUser({
user: process.env.MONGO_USERNAME ,

I created a project that integrates the truffle and react frameworks，Then I configured rinkeby test network of Ethereum in truffle-config.js.But, when I migrate the contract to rinkeby network, something went wrong.
truffle compile
truffle migrate --network rinkeby
Then came some mistakes

I wanted to lift my sails aap in production mode.when i run sails lift --prod --verbose, i am getting bunch of errors.
My local.js file looks like this.

[ Edited: the following answer was based on the original question which was completely changed by the author ]
Your sails app need to lift in production mode or you need to specify the port to be used in your config files.
Production mode runs your express server on port 80.
Is your AWS instance setup to lift the app in production mode?
http://sailsjs.org/documentation/anatomy/my-app/config/env/production-js
You don 't have connection specified for production in local.js (As you are running from your Desktop)
As the error rightly says,
connections:config[process.env.NODE_ENV].connections,
