Issue with Amazon CognitoSync + dates

[ricardclau]

Hi

I am testing the Amazon CognitoSync API and I am getting the following error with the updateRecords method:

Fatal error: Uncaught Aws\CognitoSync\Exception\CognitoSyncException: AWS Error Code: SerializationException, Status Code: 400, AWS Request ID: 4856729f-5845-11e4-95fa-c931d79f176b, AWS Error Type: client, AWS Error Message: class java.lang.String can not be converted to milliseconds since epoch, User-Agent: aws-sdk-php2/2.7.1 Guzzle/3.9.2 curl/7.30.0 PHP/5.6.2

I am adding the Request ID in case that helps...

The failing call is:

$result = $clientSync->updateRecords([
    'IdentityPoolId' => $identityPoolId,
    'IdentityId' => $cognitoId,
    'DatasetName' => 'test',
    'RecordPatches' => array(
        array(
            'Op' => 'replace',
            'Key' => 'keytest',
            'Value' => 'valuetest' . time(),
            'SyncCount' => 0,
            'DeviceLastModifiedDate' => (new \DateTime())->getTimestamp(),
        ),
    ),
    'SyncSessionToken' => $syncToken,
]);

Both $identityPoolId and $cognitoId are valid (they actually work in other calls) and $syncToken has been obtained with

$syncToken = $clientSync->listRecords([
    'IdentityPoolId' => $identityPoolId,
    'IdentityId' => $cognitoId,
    'DatasetName' => 'test',
])->get('SyncSessionToken');

Any ideas on what can be wrong?

Best

This might be a bug in how the SDK is sending the date values for this service.

1. Can you provide a wire log of the request just so we can some clarification on what is going on.
2. You might be able to patch it by putting a timestampFormat line, like in the SWF service description, into the Cognito Sync service description. Let me know if that works.

Hi @jeremeamia thanks for replying back this fast

{"Message":"class java.lang.String can not be converted to milliseconds since epoch"}

So, DeviceLastModifiedDate is in ISO8601 format which I assume is created by either the SDK or Guzzle itself?

I have also tried approach 2, but the timestamp is still serialized in ISO8601 format although I have changed cognitoSync-2014-06-30.php, am I missing something?

Please let me know if this is enough or I can help with some extra logs

Hi @jeremeamia the date formatting problem has disappeared in 2.7.2 (I patched wrongly cognitoSync-2014-06-30.php in my local code) but I am getting now a 403 credentials problem.

In the API it does not say the ClientContext is mandatory and AFAIK I am supplying all needed fields. Everything else I have tried seems to work which makes me think there is another bug here.

I am providing the logs in case they are helpful
