                    <description>&lt;p&gt;Unchecked return value&lt;/p&gt;

&lt;p&gt; If the function returns an error value, the error value may be mistaken for a normal value. Value returned from a function is not checked for errors before being used&lt;br/&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/storage/wiredtiger/wiredtiger_record_store.cpp#L685-L703&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/master/src/mongo/db/storage/wiredtiger/wiredtiger_record_store.cpp#L685-L703&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;I think it uasserts or invariantStatusOK() in every path other than when it returns true. This could mean that we don&apos;t need to check the false case explicitly, correct?&lt;/p&gt;</comment>
