Helper function to wrap Invoke result in data overridden

[hypnoslin]

gtest version: v1.11.0
Environment: Ubuntu-22.04

Let's start with an example.

This is the working one.

TEST_F(readTest, testNestedCallback)
{
    EXPECT_CALL(*mockedDev,
                read(::testing::_),
                         ::testing::_)
        .WillOnce(::testing::Invoke(
            [](uint8_t,
               const std::function<void(std::span<const uint8_t>)>& callback) {
                callback(std::span<const uint8_t>({1}));
            }));
    EXPECT_CALL(*mockedDev,
                read(::testing::_, ::testing::_))
        .WillOnce(::testing::Invoke(
            [](uint8_t,
               const std::function<void(std::span<const uint8_t>)>& callback) {
                callback(std::span<const uint8_t>({2}));
            }));

    ptr->getNested(
        [](std::string&& actual) { EXPECT_EQ(actual, "0x102");});
}

This is the failed one.

void expect(std::span<const uint8_t> data)
{
    EXPECT_CALL(*mockedDev,
                read(::testing::_),
                         ::testing::_)
        .WillOnce(::testing::Invoke(
            [data](uint8_t,
               const std::function<void(std::span<const uint8_t>)>& callback) {
                callback(data);
            }));
}

TEST_F(readTest, testNestedCallback)
{
    expect(std::span<const uint8_t> (std::span<const uint8_t>({1})));
    expect(std::span<const uint8_t> (std::span<const uint8_t>({2})));

    ptr->getNested(
        [](std::string&& actual) { EXPECT_EQ(actual, "0x102");});
}

The actual output is "0x202".
When trying to wrap the invoke, the first entrance data will be overridden by the second call.

Is this expected behavior? And, is there any alternative that can achieve the same?
I found a similar thread #2389, but it seems not to help.
