+.Errors appear when loading Observability Infrastructure inventory views after upgrading to version 8.10.0 or higher.
+[%collapsible]
+====
+*Details* +
+After upgrading to version 8.10.0 or higher, you may encounter errors when loading inventory views. 
+
+For more information, refer to https://github.com/elastic/kibana/issues/187254[#187254].
+
+*Workaround* +
+You can mitigate the issue by completing the following steps:
+
+. Search the `.kibana_*` index for `type: inventory_view`.
+
+. Copy the `_id` field, which will be formatted as `inventory-view:<id>`. For example, `inventory-view:3d3d06b0-f873-4373-8446-f6a8341cd8b1`. Omit the `inventory-view:` portion and copy only the string of `_id` characters.
+
+. The offending documents are those with fields `inventory-view.legend.steps` > 18. Delete these documents by running the following in *Console*:
+
+[source,js]
