Incompatibility between latest @nestjs/swagger 7.2.0 and @nestjs/typeorm 10.0.1 due to reflect-metadata

Is there an existing issue for this?

  • I have searched the existing issues

Current behavior

When using latest "@nestjs/swagger": "7.2.0" and "@nestjs/typeorm": "10.0.1", then the NestJS application start is failing during bootstrap with "Error: A circular dependency has been detected (property key: "level"). Please, make sure that each side of a bidirectional relationships are using lazy resolvers".

Root cause

"reflect-metadata": "^0.1.13" is required for @nestjs\swagger to work.

"typeorm":"0.3.20" was introduced by "@nestjs\typeorm":"10.0.1" installed "reflect-metadata": "^0.2.0" under node_modules/typeorm/node_modules/reflect-metadata.

When stepping through the code, for unknown reasons this wrong version node_modules/typeorm/node_modules/reflect-metadata is picked up by @nestjs\swagger instead of node_modules/reflect-metadata failing to get meta data for Swagger and causing the error

Workaround

npm install typeorm@0.3.17

Minimum reproduction code

https://github.com/snps-achim/nestjs-swagger-typeorm-problem

Steps to reproduce

Clone

git clone https://github.com/snps-achim/nestjs-swagger-typeorm-problem.git
cd nestjs-swagger-typeorm-problem

Installation

NPM
$ npm install
SQL

Also, you need an SQL server and adjust password under ./src/app.module.ts)

Running the app

$ npm run start

Expected behavior

Application shall start normally.

Instead, the following errors are provided:

npm run start

> swagger-typeorm-problem@0.0.1 start
> nest start

This should be fixed in v7.3.0 in combination with @nestjs/{core, common}@10.3.2 (nestjs/nest#13107)
