NextAuth not working behind corporate proxy : getting TypeError: HttpsProxyAgent is not a constructor

[ochaoui]

Hello folks !

How are you doing ?

i am trying to make next-auth work with my corporate proxy.

As explained here link I installed patch-package and added this patch :

diff --git a/node_modules/next-auth/core/lib/oauth/client.js b/node_modules/next-auth/core/lib/oauth/client.js
index 77161bd..1082fba 100644

+++ b/node_modules/next-auth/core/lib/oauth/client.js
@@ -7,11 +7,19 @@ exports.openidClient = openidClient;

 var _openidClient = require("openid-client");

+var HttpsProxyAgent = require("https-proxy-agent");
+
 async function openidClient(options) {
   const provider = options.provider;
-  if (provider.httpOptions) _openidClient.custom.setHttpOptionsDefaults(provider.httpOptions);
-  let issuer;
+  let httpOptions = {};
+  if (provider.httpOptions) httpOptions = { ...provider.httpOptions };
+  if (process.env.http_proxy) {
+    let agent = new HttpsProxyAgent(process.env.http_proxy);
+    httpOptions.agent = agent;
+  }
+  _openidClient.custom.setHttpOptionsDefaults(httpOptions);

+  let issuer;
   if (provider.wellKnown) {
     issuer = await _openidClient.Issuer.discover(provider.wellKnown);
   } else {

But the problem is when I run my yarn dev, I got this error :

[next-auth][error][SIGNIN_OAUTH_ERROR]

Any idea on how to fix this ?

here are the versions I use :
"next-auth": "^4.24.5",
"https-proxy-agent": "^7.0.5",
"patch-package": "^8.0.0",
"postinstall-postinstall": "^2.1.0",

In my case, I did downgrade https-proxy-agent to 5.0.0 and that solved the problem
