Error while parsing 2018-05-01T00:00:00 date using Instant.parse

Question

Here is my code which i am using to parse string using Instant.parse ,

String date = "2018-05-01T00:00:00";
Instant.parse(date)

And getting below error

java.time.format.DateTimeParseException: Text '2018-05-01T00:00:00' could not be parsed at index 19
        at java.time.format.DateTimeFormatter.parseResolved0(DateTimeFormatter.java:1949)
        at java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1851)
        at java.time.Instant.parse(Instant.java:395)

I cannot use other then Instant so looking solution for it only!

Which time zone is that local time supposed to be in? You can't parse to an instant without a time zone. If it's in UTC, you can simply add a "Z" to the end of the string before parsing. — Andy Turner, Apr 24 '20 at 13:14
I am not sure about that as i am getting it from third party api response! — Wit Wikky, Apr 24 '20 at 13:18
`2018-05-01T00:00:00` does not define a moment in time, an instant. If you can find out what time zone or UTC offset was implied, we can help you convert to `Instant`. It seems the time of day doesn’t matter, though? So why not just parse into `LocalDate`? — Ole V.V., Apr 24 '20 at 13:41

Instant.parse will only accept the string that are in ISO INSTANT FORMAT

Obtains an instance of Instant from a text string such as 2007-12-03T10:15:30.00Z.

The string must represent a valid instant in UTC and is parsed using DateTimeFormatter.ISO_INSTANT.

But the String you have represents LocalDateTime, so parse it into LocalDateTime and then convert into Instant

A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30.

LocalDateTime dateTime = LocalDateTime.parse(date);
Instant instant = dateTime.atZone(ZoneId.of("America/New_York")).toInstant();
