Description

After upgrading to Nifi 1.15.2 processor ConsumeGCPubSub fails with the following error :

ConsumeGCPubSub[id=25584328-017e-1000-1436-ae76db147150] Failed to properly initialize Processor. If still scheduled to run, NiFi will attempt to initialize and run the Processor again after the 'Administrative Yield Duration' has elapsed. Failure is due to java.lang.NoClassDefFoundError: io/grpc/internal/ManagedChannelImplBuilder$ChannelBuilderDefaultPortProvider: java.lang.ClassNotFoundException: io.grpc.internal.ManagedChannelImplBuilder$ChannelBuilderDefaultPortProvider
↳ causes: java.lang.NoClassDefFoundError: io/grpc/internal/ManagedChannelImplBuilder$ChannelBuilderDefaultPortProvider

Processor was working successfully in previous versions (1.13.2 / 1.14.0 / 1.15.0 / 1.15.1)

Steps to reproduce :

• Launch Nifi 1.15.2
  • Used docker : docker run --name nifi -p 8443:8443 -d apache/nifi:1.15.2
• Connect to Nifi instance
• Create a processor ConsumeGCPubSub and configure it with minimal settings
  • Credentials Provider Service
