Unable to obtain OffsetDateTime from TemporalAccessor: {},ISO resolved to 2024-11-26T20:55:26 of type java.time.format.Parsed

The error message you're encountering suggests that there is an issue with converting a TemporalAccessor to an OffsetDateTime. This typically happens when the TemporalAccessor does not have enough information to create an OffsetDateTime, which requires both date and time components along with an offset from UTC.

Here are some steps to troubleshoot and resolve this issue:

1. Check the Input String: Ensure that the input string contains all necessary components (date, time, and offset). For example, a valid OffsetDateTime string should look like 2024-11-26T20:55:26+02:00.

2. Use Proper Formatter: Make sure you are using the correct formatter to parse the input string. The formatter should match the structure of your input string.

3. Convert to OffsetDateTime: If you have a TemporalAccessor, you need to ensure it can be converted to OffsetDateTime. You might need to use ZonedDateTime or LocalDateTime as intermediaries if the TemporalAccessor lacks the offset information.

Here’s an example in Java that demonstrates how to handle this conversion properly:

import java.time.*;
import java.time.format.DateTimeFormatter;
import java.time.temporal.TemporalAccessor;

public class Main {
   
    public static void main(String[] args) {
   
        String input = "2024-11-26T20:55:26"; // Example input without offset
        DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE_TIME;

        try {
   
            // Parse the input string into a TemporalAccessor
            TemporalAccessor temporalAccessor = formatter.parse(input);

            // Check if the TemporalAccessor has enough information to create an OffsetDateTime
            if (temporalAccessor instanceof LocalDateTime) {
   
                LocalDateTime localDateTime = (LocalDateTime) temporalAccessor;
                // Assuming you want to convert to a specific offset, e.g., UTC+2
                ZoneOffset offset = ZoneOffset.ofHours(2);
                OffsetDateTime offsetDateTime = localDateTime.atOffset(offset);
                System.out.println("OffsetDateTime: " + offsetDateTime);
            } else {
   
                throw new IllegalArgumentException("Input string does not contain enough information to create an OffsetDateTime");
            }
        } catch (Exception e) {
   
            e.printStackTrace();
        }
    }
}

In this example:

• We first parse the input string into a TemporalAccessor using DateTimeFormatter.ISO_LOCAL_DATE_TIME.
• We then check if the TemporalAccessor is an instance of LocalDateTime.
• If it is, we convert it to OffsetDateTime by specifying a ZoneOffset.

If your input string already includes the offset, you can directly parse it into an OffsetDateTime:

import java.time.*;
import java.time.format.DateTimeFormatter;

public class Main {
   
    public static void main(String[] args) {
   
        String input = "2024-11-26T20:55:26+02:00"; // Example input with offset
        DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;

        try {
   
            // Directly parse the input string into an OffsetDateTime
            OffsetDateTime offsetDateTime = OffsetDateTime.parse(input, formatter);
            System.out.println("OffsetDateTime: " + offsetDateTime);
        } catch (Exception e) {
   
            e.printStackTrace();
        }
    }
}

This approach ensures that the input string is correctly parsed into an OffsetDateTime object.
