We are using the Tax.Avalara v1.22 plugin by nopCommerce team on a nopCommerce 3.8 site.
Maybe have had the following error appear a couple times, and this time it resulted in an order going through tax free.

Short Message:
Avalara tax request error: { "ResultCode": "Error", "Messages": [ { "Summary": "DocStatus is invalid for this operation.", "Details": "Expected Saved|Posted", "RefersTo": "DocStatus", "Severity": "Error", "Source": "Avalara.AvaTax.Services.Tax"} ] }
Full Message:
System.Net.WebException: The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse() at Nop.Plugin.Tax.Avalara.Helpers.AvalaraTaxHelper.PostTaxRequest(TaxRequest taxRequest, AvalaraTaxSettings avalaraTaxSettings, ILogger logger)

We are using the built-in one page checkout, and the relative URL that generated the error was /checkout/opcconfirmorder/.
We have had no luck recreating the issue via customer impersonation. The products in the cart were not set to tax-free, the user is not flagged as tax exempt, and other orders all appear to be pulling in correct tax rates.
Has anyone else had this issue, and found out the cause and a viable solution?
