Answer 1

The clue is in “A potentially dangerous Request.Path value was detected from the client”

Often this is triggered when html or javascript is submitted through a form or in a url, though it’s impossible to tell exactly from what you have posted.

Hopefully this might point your investigations in the right direction.
