R2DBC + spring : Failed to instantiate [io.r2dbc.pool.ConnectionPool]: Factory method 'connectionFactory' threw exception with message

Question

When trying to initialize the application, I got an error.

r2dbc + Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [io.r2dbc.pool.ConnectionPool]: Factory method 'connectionFactory' threw exception with message: Unable to create a ConnectionFactory for 'ConnectionFactoryOptions{options={database=company, host=127.0.0.1, driver=postgresql, password=REDACTED, port=5433, user=postgres}}'. Available drivers: [ pool ]

I found a solution, maybe it will be useful to someone. (for migrating scripts for databases, flywaydb is used)
