pipeline_schedules pages throwing error 500

Summary

In a self-hosted gitlab, when trying to access the new feature "Pipelines Schedules" from a project configured with previous "Scheduled Pipelines Triggers", I receive a error 500.

Steps to reproduce

  1. Use Gitlab-ce 9.1.4 to create a scheduled pipeline;
  2. Do the migration to 9.2.0
  3. Try to access git.url/group/project/pipeline_schedules

What is the current bug behavior?

Error 500

What is the expected correct behavior?

Display "Scheduling Pipelines" page
