Thanks for your issue. If you are reporting a new issue, make sure that we do not have any duplicates already exist. If it does not work with Go 1.21.0, please reference the issues #1465, #1595, #1603, #1608, #1614, #1619, #1620, #1621, #1623, #1633, #1637, #1641, #1642, #1648, #1651, #1652, #1656, #1657, #1660, #1663, #1670, #1686, #1734, #1752, #1764, #1768, #1774 and #1840. There are some incompatible changes in the Go 1.21.0 encoding/xml library. I have given feedback to the Go team and created a patch for it (golang/go#61881), and it has been fixed on Go 1.21.1. Please using the Go 1.20.14 and previous Go released version or upgrade to Go 1.21.1 and later. I have added notice on the README and documentation website for this, and I've closed this. If you have any questions, please let me know, and reopen this anytime.
