Thrown error:

Using ts-node version 8.10.2, typescript version 3.9.5 Failed creating database connections: MissingDriverError: Wrong driver: “undefined” given. Supported drivers are: “cordova”, “expo”, “mariadb”, “mongodb”, “mssql”, “mysql”, “oracle”, “postgres”, “sqlite”, “sqljs”, “react-native”, “aurora-data-api”, “aurora-data-api-pg”.

I tried to delete the folder node_modules and have it reinstalled but I always end up with the same error. I am certain that the database driver with typeorm is correctly defined. The only thing I did was upgrading the package ts-node-dev.

Did something change? I tried looking for a change log for the upgrade but couldn’t find it.

Downgrading fixed the issue again:

npm install -D ts-node-dev@1.0.0-pre.44

On a side note there’s a small typo in the README:
