I am getting a HTTP 500 when I call /api/data/v8.2/accounts?$select=accountnumber,name&$top=5 from C#. Works in a browser.

{StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:
{
Cache-Control: private
Server:
REQ_ID: 97cbcb60-1ee3-4d9e-8b1a-2241abfa5390
Persistent-Auth: true
Date: Thu, 29 Oct 2020 16:40:05 GMT
Content-Type: text/html
Content-Length: 1208
}}

Can I see more detail on the server side about the problem?

HI,

Did you check Event Log on web server?

The code I shared would work in both on-premise and Online. You can convert the response and see error reason.

You can also try enabling Trace on server then check.

Thanks but I'm on premises so I don't think that's an option
