Knex - error: password authentication failed for user "Joshua Rieth" - windows

Question

I am working on building out my PostgreSQL database with Knex and I keep getting this error when I run knex migrate:latest.
error: password authentication failed for user "Joshua Rieth"

I am assuming that is that it has to do with my username, but it should be the default postges user that I used when setting up PostgreSQL. I should also mention that the user and password is in a .env file.
Spec
PostgreSql 12
Windows 10
NPM 6.14.6
pg 8.3.0
knex 0.20.15

Answer 1

When you set up knex you need to supply the username / password, unless you'd like to connect as a "current OS user". There are multiple places where you could have set up the credentials, so it would be nice if you could check them all (and inform us :) ).
One way of doing this is:
require('knex')({
client: 'pg',
connection: 'postgres://username:password#localhost:5432/dbname'
})
Alternatively, you could set up environment variables PGUSER and PGPASSWORD, Knex connection would pick those up too.
Your connection could also be configured with full details rather than the link:
var knex = require('knex')({
client: 'pg',
version: '12.0',
connection: {
host : '127.0.0.1',
user : 'your_database_user',
password : 'your_database_password',
database : 'myapp_test'
}
});
To exclude your usernames / passwords from the actual code I would strongly suggest you use something like dotenv package: https://www.npmjs.com/package/dotenv
(NB: below is not about your specific error, as your username is not specified correctly) Another thing that I would check on Pg side is that you have enabled password authentication in your pg_hba.conf. md5 method allows for the password-hash based authentication, which should be good for you. It should look like this:
# TYPE DATABASE USER CIDR-ADDRESS METHOD
host all all 123.123.123.123/32 md5
