I’m trying to use RequestJWTUserToken on the C# SDK, but it keeps failing at “RestClient.SendRequest(Request)”.

Does anyone know what might cause the response to error?

I’ve checked and made sure the clientId = Integration Key, userId = User ID, and the string from privateKeyBytes matches my RSA Private Key. The scopes are “signature” and “impersonation”.

The request being sent has the following HeaderParams:

" Content-Type, application/x-www-form-urlencoded]",Content-Type,application/x-www-form-urlencoded
"fCache-Control, no-store]",Cache-Control,no-store
"oPragma, no-cache]",Pragma,no-cache

"-assertion, eyJhbGciOiJSUzI1NiIsIn…..
