Can't get space length via tarantool.crud about go-tarantool HOT 4 CLOSED

The error seems clear, but I can’t understand why tarantool returns 1 field when asking for length.

To be honest, it's more weird that every (or almost every) other method returns explicit result, nil in case of success.

Thank you for the issue, are you sure that go-tarantool version is exactly v2.0.0? It should be fixed with:
c3ba5b5

Please, write a crud version because I can’t reproduce the problem. It works fine for me:

// ExampleLenRequest demonstrates how to execute a LenRequest.
func ExampleLenRequest() {
	conn := exampleConnect()
	req := crud.MakeLenRequest(exampleSpace)

	ret := crud.LenResult{}
	if err := conn.Do(req).GetTyped(&ret); err != nil {
		fmt.Printf("Failed to execute request: %s", err)
		return
	}

	fmt.Println(ret.Value)
	// Output:
	// 4
}

Please, make sure that go-tarantool version is release and v2.0.0 at least (or you could use v2.1.0 to make sure).

I use github.com/tarantool/go-tarantool/v2 v2.0.0-20230823074441-d8df65dcd0f2.

Thank you. I'll try to update to 2.1.0 and will be back with feedback

from go-tarantool.

With the update to version 2.1.0 the problem disappeared.

Thank you very much for the quick response
