Currently when you extend DefaultErrorAttributes and create new object with deprecated constructor, there is no way to disable exception attribute in error output even if you specify server.error.include-exception=false in application.properties.
If this.includeException is false, it should not be included in ErrorAttributeOptions.
With this fix it should work properly, meaning if this.includeException is null or false, exception is not included.
