DescribeFeatureType response contains mixed content when one type does not exist

Issue Type:	Bug
Affects Versions:	2.21.0
Assignee:	Unassigned
Components:	WFS
Created:	23/Jun/22 3:51 PM
Environment:	CentOS 7
Priority:	Medium
Reporter:	Jason Newmoyer (SUB)

When invoking WFS 1.1.0 DescribeFeatureType using multiple types via TYPNAME param, if one of the layers is not available (or has some type of error when generating the schema), you’ll end up with mixed content in the response - basically you can end up with JSON with an XML exception concatenated to it as per below:

https://myserver/geoserver/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&outputFormat=application/json&TYPENAME=ngs:country_boundaries,ngs:land_polygons_simp
