Using ifModifiedSince with getLeaveApplicationsV2 causes an error

[haydn]

SDK:

• Version 4.35.0

Describe the bug

If you use the ifModifiedSince argument with the xero.payrollAUApi.getLeaveApplicationsV2 method you'll get a 500 error back.

To Reproduce

Steps to reproduce the behavior:

1. Set-up a client and connect it to a Xero tenant that's using AU payroll.
2. Try to retrieve the leave applications using the getLeaveApplicationsV2 method by passing both a xeroTenantId argument and any date for a ifModifiedSince argument.

Alternatively, you can see the underlying issue by doing a cURL request with the If-Modified-Since header included:

curl 'https://api.xero.com/payroll.xro/1.0/LeaveApplications/v2?page=1' --header 'Xero-Tenant-Id: {ID}' --header 'Accept: application/json' --header 'Authorization: Bearer {TOKEN}' --header 'If-Modified-Since: 2023-07-05T07:43:38.820Z'

You'll get this response back:

{"Title":"An error occurred","Detail":"An error occurred in Xero. Check the API Status page http://status.developer.xero.com for current service status.","Status":500,"Instance":"c1ba9d6b-f0c7-4109-9364-ffdb6744909e"}

Expected behavior

It should accept the header and return only the leave applications modified since the given date as documented here:

This is an error with the Xero API not an error in the SDK. A fix has been released for this within the Xero payroll API
