Long cannot be cast to LocalDateTime

It seems like you are encountering a casting issue in your code. When you try to cast a `Long` to `LocalDateTime`, it is not possible because they are incompatible types.
`Long` is a wrapper class for the primitive type `long`, which represents a signed 64-bit integer. On the other hand, `LocalDateTime` is a class from the `java.time` package that represents a date and time without a timezone.
To convert a `Long` to `LocalDateTime`, you will need to convert the epoch time (represented by the `Long` value) to the equivalent date and time using appropriate methods. Here's an example of how you can achieve this:
```java
Long epochTime = 1623123456789L; // Example epoch time
Instant instant = Instant.ofEpochMilli(epochTime);
LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, ZoneId.systemDefault());
```
In this example, we use the `Instant.ofEpochMilli()` method to create an `Instant` object based on the epoch time (in milliseconds). Then, we convert the `Instant` to `LocalDateTime` using the `LocalDateTime.ofInstant()` method, specifying the desired timezone (in this case, the system's default timezone).
Make sure to replace `1623123456789L` with your actual `Long` value.
