**Description**  
For OAuth authentication with the Zoom app  
When you access [https://zoom.us/oauth/authorize?response\_type=code&client\_id={CLIENT\_ID}&redirect\_uri=https%3A%2F%2Fpath%2Fto%2Fcallback](https://zoom.us/oauth/authorize?response_type=code&client_id=%7BCLIENT_ID%7D&redirect_uri=https%3A%2F%2Fpath%2Fto%2Fcallback) An error was encountered when processing your request" is displayed and authentication fails.

I checked the network and confirmed that [https://marketplace.zoom.us/api/v1/apps/JUHYLUdQQoKt7\_ybbqFf5g/subscriptions/@accept](https://marketplace.zoom.us/api/v1/apps/JUHYLUdQQoKt7_ybbqFf5g/subscriptions/@accept) returned a 500 error, but I haven’t been able to find out more about the cause.

**Error**

```auto
{
  code: 500;
  error: "Internal Server Error";
  message: "An error was encountered when processing your request";
  sid: "4457c4ff26b68f71";
  status: 500;
  tid: "4457c4ff26b68f71";

  trackingId: "MP_0d4970e095574e589a5d7004abea2577";
}

```

**How To Reproduce**  
Access [https://zoom.us/oauth/authorize?response\_type=code&client\_id={CLIENT\_ID}&redirect\_uri=https%3A%2F%2Fpath%2Fto%2Fcallback](https://zoom.us/oauth/authorize?response_type=code&client_id=%7BCLIENT_ID%7D&redirect_uri=https%3A%2F%2Fpath%2Fto%2Fcallback)
