  I have an issue when I import the export json file
  ## Important Details
  
  On-Premise w/ Docker, version 9.1.2
  
  ## Description
  
  I have two servers with a sentry. There are several projects on the first server, and I would like to copy these projects to the clear second server.
  I use the export/import commands. The export command works fine. However, when I run the import command, I get an error.
  
  ## Steps to Reproduce
  
  1. Run command 'sentry export sentry_export.json' on the first server
  2. Run command 'sentry import sentry_export.json' on the second server
  3. Get an error

  ### What you expected to happen
  
  Import works fine too
