Why am I getting this error: MongooseServerSelectionError: self signed certificate in certificate chain.
I’m using mongoose (v6.8.3) to connect to my mongodb database. As far as I know my code should work just fine:
let options = {
useNewUrlParser: true,
useUnifiedTopology: true,
};
const dbCertPath = path.resolve('./ca-certificate.crt');
if (envVars.CA_CERT) {
fs.writeFileSync(dbCertPath, envVars.CA_CERT);
options = {
useNewUrlParser: true,
useUnifiedTopology: true,
ssl: true,
sslCA: `${dbCertPath}`,
};
}
mongoose
.connect(mongodbUrl, options)
.then(() => {
logger.info('Connected to MongoDB');
})
.catch((error) => {
logger.error(error);
});

Hello @ricardodolnl
This seems be to an expected behavior since MongoDB does more strict validation on SSL certificate.
A similar error was reported in GitHub which you can check here. There is also a proposed quick if which you can also try to implement

Hope that this helps!
