Elastic Transcoder "Start of list found where not expected"

Question

I am having trouble using Elastic Transcoder in PHP. I am trying to use transcoder to grab an audio file from S3, trim it, and place it back. When I try to use the following job creation code I am getting the error: "{"Message":"Start of list found where not expected"}"

When I try to create a JOB I use the following code:

$createJobResult = $transCoderClient->createJob([
    'PipelineId' => {pipelineID},
    'Input' => [
            'Key' => $media->key
        ],
    'Outputs' => [
        [
            'Key' => $newMedia->key,
            'PresetId' => {$presetID},
            'Composition' => [
               [
                   'Timespan' => [
                       'StartTime' => $trimStart,
                       'Duration' => $duration
                       ]
                   ]
               ]
           ]
       ],
       'UserMetaData' => [
           'trimJobId' => $trimQueueEntry->id
       ]
   ]);

can anyone weigh in on this problem and help? When looking at the documentation on Amazon the structure looks alright.

Figured out the answer after much searching. Here was the proper structure.

$createJobResult = $transCoderClient->createJob([
                'PipelineId' => '{pipelineID}',
                'Input' => [
                    'Key' => (string) $media->key,
                ],
                'Inputs' => [
                    [
                        'Key' => (string) $media->key,
                        'Timespan' => [
                            'StartTime' => 00:00:00.000,
                            'Duration' => 00:00:25.000
                        ]
                    ]
                ],
                'Output' => [
                    'Composition' => [
                        [
                            'TimeSpan' => [
                                'StartTime' => 00:00:00.000,
                                'Duration' => 00:00:25.000
                            ],
                        ],
                    ],
                    'Key' => $newMedia->key,
                    'PresetId' => {presetID},
                ],
            ]);
