Has anyone seen this error before on Customer Refunds? Obviously no line items to enter or check for Slack Conversation

Interesting, I had a user report this error the other day.

@Josh Godfrey did not find more information unfortunately. The end user ended up crediting with credit memo or credit balance (via JE) - Kevin J of Kansas suggested and that seems to have worked. Then we got another error with closed accounting period but that was a different one.
