Can't export PDF figure

[cmmercer]

When trying to export a PDF figure from pipeline, I get a stack trace (see below). Is this due to a missing package perhaps?

Traceback (most recent call last):

I had reportlab 3.6.8 installed; reverting to 3.5.59 has fixed the issue, I can now export PDFs. Thanks!
