Hi,

Are you inserting that URL into your browser?

Have you tried to encode the slash between SubjectId/rabbits as SubjectId%2Frabbits instead?

Rather than:

https://BASEURL.ORG/query/MYPROJECT/selectRows.api?schemaName=study&query.queryName=Demographics&query.SubjectId/rabbits~eq=rabbits

You'd use:

https://BASEURL.ORG/query/MYPROJECT/selectRows.api?schemaName=study&query.queryName=Demographics&query.SubjectId%2Frabbits~eq=rabbits

This should also work as well.

Regards,

Jon
