I need to proxy a request from an Angular app to a non-CORS endpoint.

Here’s my request handler in Express:

export const cqlTranslation = (environment: IEnvironment): Router => {
  const router = express.Router();
  const multerData = multer();

  router.post('/', multerData.none(), async (request: Request, response: Response) => {

    try {
      const data = (await axios.post(environment.translator.api, request.body, {
        headers: request.headers,
        params: request.params,
        httpsAgent: new https.Agent({
          rejectUnauthorized: false,
        }),
      })).data;

      response.send(data);
    }
    catch (error) {
      console.log(error);

      response.sendStatus(400);
    }

  });

  return router;
}

What I’m getting back is:

authorizationError: 'ERR_TLS_CERT_ALTNAME_INVALID'

I have tried setting NODE_TLS_REJECT_UNAUTHORIZED:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

but that’s not working. Suggestions in these posts:

https://github.com/axios/axios/issues/1650

aren’t working either. What are some other options / alternatives I can try?
