Answer 1

This error is common in Umbraco upon XSLT parsing as the parser assumes that some of your data may be null/empty, when in reality it may be [always] assigned.

The trick is find the culprit line of code and enclose it a test-for-empty-if-block.

For example, it may or may not be this line, although it quite commonly occurs with @id and NiceUrl():

<xsl:otherwise>
    <xsl:if test="@id != ''">
        <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:value-of select="@nodeName"/>
        </a>
    </xsl:if>
</xsl:otherwise>

The error is likely to arise from the GetMedia()¹ or NiceUrl()² calls as they require a parameter of type Int32 to be passed, but I can see you’ve already enclosed your GetMedia() call in an if-block.
