> After upgrading to Nifi 1.15.2 processor ConsumeGCPubSub fails with the 
> following error :
> {noformat}
> 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{noformat}
> 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
>  ** Project and suscription
>  * Link it to another created processor (used DebugFlow)
>  * Start processors
