This example is important, because it declares xsd:anyURI as datatype for a column containing URI's as values. That particular part actually goes well.

The errow thrown here is that "https://iisg.amsterdam/{_row} does not look like a valid URI, trying to serialize this will break." This is actually default behaviour and probably linked to the jinja templating as well.
