Error "Invalid scheme, expected connection string to start with "mongodb://" or "mongodb+srv://""

I have an error that blocks me, have you ever encountered this error?

File .env =>

DB_CONNECT = 'mongodb+srv://';


const dotenv = require("dotenv").config();
mongoose.set("strictQuery", false);

mongoose.connect(process.env.DB_CONNECT, {

    useUnifiedTopology: true,

    useNewUrlParser: true,

}).then(console.log('connect sucess to mongodb'))

bot.ticketTranscript = mongoose.model('transcripts',

    new mongoose.Schema({

        Channel : String,

        Content : Array



Error =>

throw new MongoParseError('Invalid scheme, expected connection string to start with "mongodb://" or "mongodb+srv://"');

MongoParseError: Invalid scheme, expected connection string to start with "mongodb://" or "mongodb+srv://"

Thanks you in advance

Hello @bill, Welcome to the MongoDB community forum,

Can you please make sure by consol print this variable process.env.DB_CONNECT has the correct connection string?

Hi, thanks you for answer,

console display


With ’ ';

It’s normal ?

It looks good, check out the documentation, I think you are missing something debug your code step by step,

Out of the question, If you are using mongoose latest version then don’t need to pass useUnifiedTopology: true, and useNewUrlParser: true in connection because by default it set true

it not

remove the quotes and if it still does not work remove leading and trailing spacss

The trailing semicolon is probably erroneous too.

[MONGOOSE] DeprecationWarning: Mongoose: the strictQuery option will be switched
back to false by default in Mongoose 7. Use mongoose.set('strictQuery', false); if you want to prepare for this change. Or use mongoose.set('strictQuery', true); to suppress this warning.

Invalid scheme, expected connection string to start with “mongodb://” or “mongodb+srv://”

both the error will be gone
first use the
// mongoose.set(‘strictQuery’, true) in top
and remove the extra space in the link of mondodb

remove the ‘;’ from the last of .env file, and it will work

why are you storing string value in env??? and also why ‘;’
This should be-

DB_CONNECT = mongodb+srv://

Thanks your suggestion worked. It was this removing ‘;’ semicolon at the end.

bro which line of the code remove the '" ; " plz tell me

The line which is having your connect string.Remove semicolon at the end of connect string
Please scroll to top of this thread where you see DB_CONNECT = ‘your_connect_string’; <------------ remove this semicolon
