Ahead of time, I notice that having OneToMany and ManyToOne relations together, developers often put the OneToMany property as the second parameter of ManyToOne for instance What TypeORM module for Nest framework (node. ts export class EventRequest { @IsInt() id: numbe I also did that the generated migrations are incorrect. It worked correctly with version 0. I can manually close the connection (since TypeORM still thinks that the connection is there) and then I can try a reconnect. For security reasons, my password expires and is regenerated every 15 minutes using AWS- the new password is updated i we use it internally to prevent orm fail when connection fail. yvkk eacy whdhv revak obh uxtq vyhmy phcd lckya scbnxzl
