As reported https://forum.image.sc/t/omero-mapr-questions/50843, this is 1 of the 2 errors from "second issue" and reproduced on IDR:
When a mapr Value is selected in the Tree (see screenshot) mapr tries to load Annotations for it in the right panel.
However, the webclient rendering of these map annotations expects each to have a link (to show what object each is linked to:
# webclient mapanns_underscore.html
<!-- If single object show e.g. Image ID: (slice ImageI -> Image) -->
<b><%= ann.link.parent.class.slice(0, ann.link.parent.class.length-1) %>
ID:</b> <%= ann.link.parent.id %><br />
and this isn't loaded by mapr, so we get the error above.
