• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 1.4.0
• Fix Version/s: 1.5.0
• Component/s: Core Framework
• Environment: Running NiFi 1.4.0 on a small 3 node cluster (Ubuntu 14.04.5 LTS), configured to use the OIDC for Auth. I setup the ssl/tls using the nifi-toolkit for the cluster config.

Description

We're trying to migrate from a unsecure NiFi 1.3.0 cluster (everything working in the NiFi 1.3 cluster) to a secure 1.4.0 cluster. When we try to start the configured InvokeHTTP processor, we're seeing the following in the logs:
