I had a look at this error and can confirm that it's a legit error with the
main branch. So an Issue in Jira would be welcomed.
Carsten provided two different sld. Here is the one I've been using:
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">
<ogc:Function name="Interpolate">
<ogc:Function name="env">
<ogc:Literal>wms_scale_denominator</ogc:Literal>
</ogc:Function>
<ogc:Literal>2132</ogc:Literal>
<ogc:Literal>#AA3333</ogc:Literal>
<ogc:Literal>17471320</ogc:Literal>
<ogc:Literal>#AA9999</ogc:Literal>
<ogc:Literal>color</ogc:Literal>
</ogc:Function>
</CssParameter>
<CssParameter name="stroke-width">
<ogc:Literal>2</ogc:Literal>
</CssParameter>
</Stroke>
</LineSymbolizer>
And here is a full stack trace:
