From the looks of things it's the exact same issue at the same customer. I don't know if Jerry ever resolved it. I've attached the log entry that's showing the error. It's using Idb and Chris 21 versions 4.1.x. Their Chris21 instance is version 8.16.17.
Adam suggested running some Chris 21 query as a resolution but I'm not sure where that query should be run. Is this likely to be a misconfiguration of Chris21 or something with IdB? This is in a test environment.
Please let me know if you need any more information.
