During an update of the system, an API was changed in a way that the Content-Type of the API response changed.
When Accedo One make a new release all API responses and headers are checked for backwards compatibility to make sure there is no change in the behaviour. A human error made one api call being missed in this test list. The API was functioning correctly and there were no errors in the logs but there was a difference in the Content-Type of the response.
Accedo One Product Team rolled back the configuration that caused this change and released a new version that was stable again. We will add backwards compatibility tests for the missing API so any kind of changes in the response are caught in the future.
