IO Error:{0}

Error message

IO Error:{0}

What it means

ParseConfigError wrapper for an underlying std::io::Error raised while reading the notification configuration stream (the parser reads from an io::Read source). The io error is embedded; it distinguishes transport/read failure from XML content problems, so callers can retry the read instead of reporting invalid XML.

Solutions

1. Check the wrapped I/O error (truncated body, broken stream, permissions)
2. Resend/reload the configuration once the I/O condition is fixed
