Error with wikidata-todo/wdq2graph.php

[Finn Årup Nielsen]

(I hope this is the relevant area for reporting bugs concerning wdq2graph.php)

The following link gives (presently!) an error:

https://tools.wmflabs.org/wikidata-todo/wdq2graph.php?q=19590089&props=22%2C26%2C7&lang=en&format=dot&doit=Generate+Graph

And it seems that it is not just this item and property.

The error messages I get are:

Notice: Trying to get property of non-object in /data/project/wikidata-todo/public_html/wdq2graph.php on line 35

Warning: Invalid argument supplied for foreach() in /data/project/wikidata-todo/public_html/wdq2graph.php on line 35

Notice: Trying to get property of non-object in /data/project/wikidata-todo/public_html/wdq2graph.php on line 37

Warning: implode(): Invalid arguments passed in /data/project/wikidata-todo/public_html/wdq2graph.php on line 37

There was an error running the query [You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1]

The Taxa example still works.
