I currently have a Nestjs server setup and am attempting to perform an Axios request when one of the endpoints is hit with a GET request. Here is the controller.ts code:

@Controller()
export class TestController {
    constructor(private readonly testService: TestService) {}

    @Get('testData')
    testData() {
        return this.testService.testData();
    }
}

Service.ts:

@Injectable()
export class TestService {
    status(): string {
        return 'OK'
    }

    testData(): Promise<any> {
        return helper.getTestData();
    }
}

Where helper.getTestData() is just a call to a helper file with the following function:

export async function getTestData(): Promise<any> {
    const result = await axios({
        url: tempURL,
        method: 'GET',
        timeout: 3000,
        httpsAgent: new https.Agent({
            rejectUnauthorized: false,
        }),
    });

I am able to hit this endpoint tempURL but encounter the following error message: Cannot read property 'Agent' of undefined. I know that the endpoint I am attempting to hit requires a cert, which is why I must include the httpsAgent argument inside the Axios request. If I don't include the httpsAgent argument, I receive the following message Error: unable to verify the first certificate in nodejs.

Is there a way to configure Nestjs to work with https? Or is there another way to handle this authorization issue inside of Nestjs? Using Postman everything works fine so I'm assuming it is a Nestjs issue. Any help is appreciated.

• javascript
• typescript
• https
• axios
• nestjs

• looks like https is undefined somehow – Micael Levi Commented Jul 3, 2021 at 21:42
• @MicaelLevi https is defined, I have it properly imported into the file. Also, https is a native module, how could it be undefined? – Andrew Commented Jul 3, 2021 at 23:29
• 1 depending on how you're importing it, it could. The line in the stack trace that the error Cannot read property 'Agent' of undefined appears is the same of the httpsAgent: new https.Agent one? – Micael Levi Commented Jul 3, 2021 at 23:32
• @MicaelLevi Yes, the error is on the httpsAgent: new https.Agent line. I import currently as follows: import https from 'https'; at the top of the file. – Andrew Commented Jul 3, 2021 at 23:42
• 1 @MicaelLevi you were correct, the issue was with how I was importing. import https from 'https' did not work but import { Agent } from 'https' did. Thank you! – Andrew Commented Jul 3, 2021 at 23:52

1 Answer 1

instead of import https from 'https'; you should use the namespace import: import * as https from 'https'; or set the esModuleInterop to true in your tsconfig file (under pilerOptions)
