site_scoped_certificates_enabled (and currently end_to_end_encryption_enabled) come from get_three_state_flag(return_label=True), which returns the strings 'true'/'false'. Passing these strings directly into the Site(...) model will serialize as JSON strings (or potentially raise if the model validates types) rather than booleans. Convert these values to booleans (e.g., val == 'true') before constructing Site, keeping None as-is, to match the behavior already used in update_webapp.

   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
   desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
   and secure permission from the new employer before Submitting those Submissions.

  Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute
  the Submission and such derivative works, and to sublicense any or all of the foregoing rights to third
  parties.
