Based on the description, it sounds like it would be worth raising an issue with Spring Vault. The NiFi implementation delegates HashiCorp Vault authentication handling to Spring Vault, so if support were introduced there, that would be ideal.

The error message we get lines up with this, and if we use an EC2 instance with IMDSv2 set to “Optional” we don’t get the error. Does that help or can I get you anything else?
