JSON de/serialization error

[DeanOutlaw]

Using the createPayRun in the AU payroll SDK sample returns error
Error occurred during JSON de/serialization. Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'Paycycle.API.DTO.AU.PayRun.UpdatePayRunRequest' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'PayrollCalendarID', line 1, position 21.
I copied the example code directly into my script and replaced the setPayrollCalendarID and other settings.

I realise this is old, but the answer might help someone else.

createPayRun is expecting an array of payruns, not a single payrun. Wrap the payrun in an array, and it should work.

$payRunResult = $obj->payrollAuApi->createPayRun($obj->tenant_id, [$payRun]);
