+.API default error code is now 500.
+[%collapsible]
+====
+*Details* +
+Previously, when {fleet-server} encountered an unexpected error it resulted in a `Bad Request` response.
+
+*Impact* +
+Now, any unexpected error returns an `Internal Server Error` response while keeping most of the current behavior
+unchanged. On expected failure paths (for example, Agent Inactive, Missing Agent ID, Missing Auth Header) a `Bad Request` response is returned. For more information, refer to {fleet-server-pull}2531[#2531].
