// context.middleware.ts
export const ctxSession = cls.createNamespace('my session');
@Injectable()
export class RequestContextMiddleware implements NestMiddleware<Request, Response> {
use(req: Request, res: Response, next: () => void) {
ctxSession.run(() => {
ctxSession.set('ctx', {

}
}
// typeorm-logger.ts
export class OrmLogger implements Logger {
logQuery(query: string, parameters?: any[], queryRunner?: QueryRunner) {
console.log('startTime', ctxSession.get('ctx')?.startTime); // output > startTime 2022-04-13T09:54:21.628Z
}
logQuerySlow(time: number, query: string, parameters?: any[], queryRunner?: QueryRunner) {
console.log('startTime', ctxSession.get('ctx')?.startTime); // output > startTime undefined
}
}Why does this problem occur and is there a solution？
