**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";

timestamp: 1677737799502;

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)
