Answer 1

我已经解决了错误。

我让adminjs模块在初始化前等待5秒:

import { AdminModule as AdminJsModule } from '@adminjs/nestjs';
import { adminModuleOptions } from './admin-module.options';
AdminJsModule.createAdminAsync({
useFactory: async () => {
await new Promise((resolve) => setTimeout(resolve, 5000));
return adminModuleOptions;
},
}),

然后我让mongoose模块在连接前等待5秒:

MongooseModule.forRootAsync({
useFactory: async (): Promise<MongooseModuleOptions> => ({
uri: mongoCredentials.url,
connectionFactory: () => {
const connection = mongoose.connection;
setTimeout(() => mongoose.connect(mongoCredentials.url), 5000);
return connection;
},
}),
}),
