Using put Email processor in NiFI java.lang.NullPointerException: java.lang.NullPointerException

[#1]

Hi all,

I am trying to integrate sending emails from NiFi using the put email processor. Below is my configuration:

When I start the processor I get this error:

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.NullPointerException: java.lang.NullPointerException

Do you have any advice regarding the configuration?

Thanks

There is not enough information provided to provide a good response here.

1. Providing the full stack trace output from the nifi-app.log may provide details that are helpful here (challenging considering the NPE nature of the exception)
2. Are you sure the SMTP server supports username and password authentication and not OAuth2 based authentication instead? PutEmail Additional Details
