I face an HTTP 400 error when creating Jira issues via JiraRestClient in Java. Downgrading client versions didn’t help. Example below:

@SneakyThrows
public TicketResponse buildTicket(TicketCategory category) {
    return jiraInterface.getTicketClient().submitTicket(
        TicketBuilder.createTicket()
            .assignProject("PROJ101")
            .setType(category.getCode())
            .setSummary("Integrate new dataset")
            .setNotes("Issue description goes here")
            .build())
        .onError(err -> logger.error(err.getMessage()))
        .obtain();
}

Based on previous experience with similar issues, I encountered a situation where HTTP 400 errors were due to an incorrect payload structure rather than client version problems. In my case, careful examination of the JSON being sent revealed that some fields did not match the expected naming or required value format mandated by the project settings. Debugging by logging the complete payload often helps uncover such discrepancies. It was also useful to cross-check the server documentation for any mandatory fields that might be absent or incorrectly formatted in the request.

While I haven’t faced the exact HTTP 400 error, I did encounter a comparable issue where the problem was actually tied to how the Java client compiled the JSON payload. In my experience, the root of the error was that the underlying data model did not perfectly match the expected format for the Jira REST API. I resolved it by deeply reviewing the API documentation and logging the actual payload sent by the client. It turned out some fields required specific formatting or data types. Consider enabling detailed logging to capture the outgoing request, then verify each field against the API’s schema to identify any unnoticed discrepancies.

hey, i had a simlar issue where the JSON structure missed a required field. try logging the complete payload to see if any mandatory data is missing or misformatted. sometimes even small typos in field names can cause the 400 errors
