Blueprint validation failures not returned to web UI

[ekoyle]

Describe the bug It appears that the logs returned by Importer (from authentik.blueprints.v1.importer) now return LogEvent objects rather than dict, which causes an exception during the handling of failed validation. I'm assuming that changing to x.event in place of x["event"] would resolve this. Here is the traceback:

builtins.TypeError: 'LogEvent' object is not subscriptable

To Reproduce Steps to reproduce the behavior:

1. Go to admin -> customization -> blueprints
2. Add or update a blueprint that will fail validation (I was using internal , not sure whether the others are affected)

Expected behavior Some kind of error including the validation error log message.

Version and Deployment (please complete the following information):
