Setup:
- Version 8.15.0 of kibana/elasticseach
- Create an application where kibana is hosted as an IFrame.
- Make serveral selections on the different dashboard.
- Navigate to other dashboards via drilldown
When changing the IFrame pointing to another dashboard an error appears
Error encountered while fetching unsaved changes: Cannot read properties of undefined (reading 'viewMode')
The only way to get around is to remove all concerned dashboards and load them again via import in saved objects .
This error was not appearing in version 8.8.0
