Trying to upload a letterhead image

[Menno-Logitrade]

The Image upload seems te be broken or I am doing something wrong.

I want to upload an image to FedEx to later use that in my letterhead and signature. I want to reference that image later on as 'IMAGE_1'

I'm trying to use it like this:

I have a working $connector

        $image1 = base64_encode(file_get_contents(__DIR__.'/files/image.png'));

        $apiDocuments = $connector->tradeDocumentsUploadV1();

        $documentRules = new DocumentRules("LetterheadSignature");
        $documentMeta = new DocumentMeta('LETTERHEAD','IMAGE_1');
        $document = new Document(
            'IMAGE_1',
            'letterhead.png',
            'image/png',
            $documentRules,
            $documentMeta
        );
        $imageUploadService = new FullSchemaImageUploadServiceInputVo($image1,$document);
        $uploadResponse = $apiDocuments->imageUploadServiceInfo($imageUploadService);

I get this error:

[InvalidArgumentException] The value array must only contain Saloon\Data\MultipartValue objects.

For some reason it does not want to accept a string as the "attachment" input. But the specifiactions does say I should input a string here:

final class FullSchemaImageUploadServiceInputVo extends Dto
{
    /**
     * @param  
final class FullSchemaImageUploadServiceInputVo extends Dto
{
    /**
     * @param  string  $attachment  Input the actual image file to be uploaded.
     * @param  Document  $document  Indicate the image reference metadata details.
     */
    public function __construct(
        public readonly string $attachment,
        public readonly Document $document,
    ) {
    }
}

The fedex documentation is wrong according to this post. So this autogenerated API would also be wrong then...

Thanks for the report, we will test this as well. Note, the FedEx REST API is according to FedEx still in a "pilot phase" so we expect there to be changes in the coming months. I recommend you request an exemption from the August 31 deadline if you are having any troubles with the current API.
