In order to run Pathfinder, a MySQL database must be set up. Please adjust the application.properties accordingly. A default docker container might look like this:
docker run -d --name mysql2 -e MYSQL_ROOT_PASSWORD=pathfinder -e MYSQL_DATABASE=pathfinder -p 10306:3306 mariadb
With the corresponding application.properties entry:
spring.datasource.url=jdbc:mysql://127.0.0.1:10306/pathfinder?useSSL=false
spring.datasource.username=root
spring.datasource.password=pathfinder
