Can't loading template during the gen

[tuxoo]

good afternoon

I've tried to generate a tracing wrapper by my custom teplate which is uploading from github https://github.com/XeniaBgd/templates/blob/main/tracing

The command is :
gowrap gen -p ./internal/domain/repository -i Repository -t https://raw.githubusercontent.com/XeniaBgd/templates/main/tracing -o ./internal/providers/analytics/tracing.go

But I've got this error:
"failed to load template: open https://raw.githubusercontent.com/XeniaBgd/templates/main/tracing: The filename, directory name, or volume label syntax is incorrect"

I've checked code
https://github.com/hexdigest/gowrap/blob/master/cmd_generate.go#L191

func underlyingErrorIs(err, target error) bool {
// Note that this function is not errors.Is:
// underlyingError only unwraps the specific error-wrapping types
// that it historically did, not all errors implementing Unwrap().
err = underlyingError(err)
if err == target {
return true
}
// To preserve prior behavior, only examine syscall errors.
e, ok := err.(syscallErrorType)
return ok && e.Is(target)
}

My error was "internal/syscall/windows.ERROR_INVALID_NAME (123)". That's why the function above returned false.

//if !os.IsNotExist(err) {
// return
//}

Without this code everything is ok.

Could somebody explain me why was that?
