Triggering logic with an ID of 0 has an invalid period

In Preview and Publish: Publish, I now suddenly get an error that did not occur with the same json before: “Triggering logic with an ID of 0 has an invalid period”
No errors found when validating my json against “
No problems in testing my schedule.
This error dis now generated for all my previously published surveys.

Example of triggering_logic that now causes this problem:

  "triggering_logics": [
      "notifications": [
      "type": "time",
      "id": 0,
      "schedule": {
        "time_format": "relative",
        "base": "registration_time",
        "period": {
          "start": "0 00:00:00",
          "randomization": {
            "function": "uniform"
          "end": "0 00:00:00"

Hi @janhoutveen

Thanks for reporting this. There was an issue with the validators in the Survey Editor. We resolved the issue. If you refresh your browser, you should not get this error anymore.
