Can't successfully start project

[koevskinikola]

Hi,

I've been trying to start a project without success. I create the project using the generator. I use a MySQL database and enter the correct credentials for the database in the /config/env/development.ts

When I try to start the server with 'yarn start' it fails. First, it asks for a mysql2 package, I install it and then I get the following error:

 code: 'ER_TOO_LONG_KEY',
 errno: 1071,
 sqlState: '42000',
 sqlMessage: 'Specified key was too long; max key length is 767 bytes',

Do you know what the problem is?

UPDATE:
Fixed this by setting the String lengths in user.model.ts to 125. However, now I get this error when I try to register a user:

Also, it doesn't seed the database. Tried it with MySQL and SQLite, same error occurs.

Thanks,
