Hi Matt,

If attaching the file isn't working, feel free to email it to support@labkey.com and reference this support forum post in your message.

We suspect that a 3rd party module (like the keim one you observed) implementation of a webpart is triggering this problem, but has been better enhanced in LabKey 17.1 to allow you as the user to see more details related to the error message.

Regards,

Jon
