Answer 1

The error coming from the YAML parser is misleading - it is not actually username: javatechi that is incorrect.
Please have a read through the YAML spec, 2.1 Collections and its examples, which is introduced with:
2.1. Collections
YAML’s block collections use indentation for scope and begin each entry on its own line. Block sequences indicate each entry with a dash and space (“- ”). Mappings use a colon and space (“: ”) to mark each key/value pair. Comments begin with an octothorpe (also called a “hash”, “sharp”, “pound” or “number sign” - “#”).
In other words it is actually the previous line that is incorrect:
url:jdbc:jdbc:sqlserver://xxxx.database.windows.net:1433;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;
You can fix it by adding a space after the url: key to seperate it from its value:
url: jdbc:jdbc:sqlserver://xxxx.database.windows.net:1433;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;
