             Summary: StandardOauth2AccessTokenProvider support forcing HTTP protocol to 1.1
                 Key: NIFI-10842
                 URL: https://issues.apache.org/jira/browse/NIFI-10842
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.18.0
            Reporter: Curtis W Ruck


We are trying to use nifi's StandardOauth2AccessTokenProvider to enable authentication in concert with InvokeHTTP to make requests to a REST API. The OAuth2 server is responding with a HTTP 408 error code, and okhttp3 is throwing a "stream was reset: HTTP_1_1_REQUIRED" exception.

In the same manner that InvokeHTTP got the `HTTP/2 Disabled` property, it would be nice if StandardOauth2AccessTokenProvider had the same property.
