Your example query works fine for me, as does the API Browser for your repo. I'm wondering if this problem might be a caching issue. I think the API team has all finished work for the week, so we won't be able to debug this until Monday. In the meantime, can you let me know if it resolves itself?
Hi Sam,
Fortunately, your team was very quick to revert back to the old version of the API.
The error was due to a bug in the new version of the Prismic API (bulk actions)
Thanks a lot
David
