OnlyOffice Version History — changesUrl Incompatibility Issue

Hey @Adam11, :wave:

Thanks for the detailed report and for sharing all the verification steps — it’s very helpful!

A few quick notes first:

  • You’re currently on Document Server 9.2.0. The latest stable version is 9.3.1, and 9.4 is scheduled for the end of April. So we recommend updating first and re-testing.

Since this is an integration issue (involving onRequestHistory, onRequestHistoryData, setHistoryData, and changesUrl), it will take time to investigate. :writing_hand:

To move forward faster, could you please provide:

  1. Server logs (and extended logs if possible) from the moment the error occurs.
  2. A short video showing the reproduction steps (loading version history → switching versions → error appearing).
  3. Confirmation that you implemented version history exactly as described in the official docs:

If this is time-critical for your project, I’d also recommend considering a paid license with dedicated professional support — they can dive into your specific integration much faster:
