How to get https API response body on proxyRes

Hello all!

I have an http and an https API.

When I use http API, when user login successfully I get access token on proxyRes and I add HttpOnly Cookie. This is working.

But when I use https API I can't get response body. In my opinion because the response body is encrypted.

How can I solution this problem. Is there a solution?

This my code snippet;

function interceptLoginResponse(proxyRes, req, res) {
            // Read the API's response body from 
            let apiResponseBody = ''
            proxyRes.on('data', (chunk) => {
                chunk = chunk.toString('utf-8');
                apiResponseBody += chunk
            })


            proxyRes.on('end', async () => {
                try {
                    // Extract the authToken from API's response:
                    const {access_token} = await JSON.parse(apiResponseBody);
            
                    const cookies = new Cookies(req, res, {secure: true})

                    await cookies.set('access_token', access_token, { secure:true, pat:"/", httpOnly: true, sameSite: 'Strict', expirationDate:"21 Oct 2022 07:28:00 GMT"})
                    await res.status(200).json({ success: true })
                } catch (err) {
                    reject(err)
                }
            })
        }
