apache-nifi - NiFi InvokeHTTP 处理器：在 NiFi 1.10.0 上 OK，在 NiFi 1.11.4 上错误 okhttp3.internal.http2.ConnectionShutdownException

Question

我有一个简单的InvokeHTTP Prozessor

Method: POST
Remote URL: https://(ServerName)/auth/realms/Sherlock/protocol/openid-connect/token
Content-Type: application/x-www-form-urlencoded
Body: grant_type=client_credentials&client_id=${client_id}&client_secret=${client_secret}

在我的NiFi 1.10.0系统上一切正常

但在NiFi 1.11.4系统上，我得到：

2020-07-28 13:11:44,256 ERROR [Timer-Driven Process Thread-9] o.a.nifi.processors.standard.InvokeHTTP InvokeHTTP[id=c9df8eec-b142-3243-52f1-b9351feb6705] Routing to Failure due to exception: okhttp3.internal.http2.ConnectionShutdownException: okhttp3.internal.http2.ConnectionShutdownException

    ...

有任何想法吗？

坦率
