BIGIP ASM Json File Upload Violations

You might be able to create an allowed URL exception in the policy for uploaded JSON content by creating an allowed URL and then not inspecting body content. Try this:

1. Go to Security ›› Application Security : URLs : Allowed URLs : Allowed HTTP URLs and create/add the URL that is associated with the uploaded JSON data. This is will be your allowed URL.
2. Change the view to Advanced, then uncheck the Staging checkbox.
3. Click Header-Based Content Profile
4. Request Header Name: Content-Type
5. Request Header Value: json/text--the value appropriate for your app
6. Request body handling: Do nothing.

Does that help?
