Unclear and not accurate error messages? Dealing with it? #1

[VaderCoinCryptoNote]

I have a Litecoin based Altcoin running and now I want to set up a mining pool for it, however Miningcore starts with such a lot of errors that I have no idea which error is the cause.

My Altcoin is based on the latest version of the Litcoin core.
I used the example config.
Why is the error not unique?
