API Error during productWithMediaGallery invokation => Property :"EntryData" does not exist

[naspar]

Hello Team,

I am facing a weird issue while trying to create/import a new product into M2 by using the API service.

Here is the API I am using :
Catalog - ProductRepositoryInterface - productWithMediaGallery
http://devdocs.magento.com/guides/v1.0/rest/restApi/restCollection/Magento/Catalog/Api/ProductRepositoryInterface/productWithMediaGallery.html

here below the error I found in the exception log while hitting the API service :

main.CRITICAL: exception 'Exception' with message 'Report ID: webapi-558da858ef77e; Message: Property :"EntryData" does not exist in the provided class: "Magento\Framework\Api\Data\ImageContentInterface".' in /home/user/workspace/public_html/lib/internal/Magento/Framework/Webapi/ErrorProcessor.php:194

and here below the json used during the HTTPcLient post invokation :

{"product":{"visibility":4,"attribute_set_id":4,"type_id":"simple","price":"45.0","media_gallery_entries":[{"types":["image","small_image"],"disabled":false,"position":1,"content":{"entry_data":"_9j_4AAQSkZJRgABAQEAYABgAAD__gAyUHJvY2Vzc2VkIEJ5IGVCYXkgd2l0aCBJbWFnZU1hZ2ljaywgejEuMS4wLiB8fEIy_9sAQwAGBAUGBQQGBgUGBwcGCAoQCgoJCQoUDg8MEBcUGBgXFBYWGh0lHxobIxwWFiAsICMmJykqKRkfLTAtKDAlKCko_9sAQwEHBwcKCAoTCgoTKBoWGigoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgo_8AAEQgBdQH0AwEiAAIRAQMRAf_EABwAAAICAwEBAAAAAAAAAAAAAAECAAMEBQYHCP_EAD8QAAE...<cutted_here>","mime_type":"image\/type","name":"pic_name"}}],"name":"product_name","sku":"26184971166","status":1,"custom_attributes":[{"value":"product_name","attribute_code":"description"}]}}

and as last, my piece of java code I have been using to import category and product - just want to mention that post/get calls are working fairly smoothly except the aforementioned error :

StringEntity input = new StringEntity(productObj.toJSONString(),"UTF-8");

            input.setContentEncoding("UTF-8");
            input.setContentType("application/json;charset=UTF-8");
            post.setEntity(input);

            HttpResponse response = client.execute(post);

            if (response.getStatusLine().getStatusCode() != 200) {
                System.out.println("Response Code\t: " + response.getStatusLine().getStatusCode()+"\n");
                System.out.println("Response Code\t: " + response.getStatusLine().getReasonPhrase()+"\n");
            }

Just let me know if you need more info .. many thanks for all your commitment in making this framework so amazing !!

Hi Guys .. any advice / fix for this issue ?

it is very critical as i can't insert products and link images using the API service.

I am getting error 500 from the server , the API service can't manage the request or properly handle the error exception.

Please let me know if you need more info from my end.

Thanks,

[joanhe]

Thanks @naspar for reporting this issue. Internal issue MAGEDOC-2426 is created to update the document.

Can you change your media_gallery_entries data to be:

"media_gallery_entries": [
    {
        "types": ["image","small_image"],
        "disabled":false,
        "position":1,
        "content":{
            "base64_encoded_data" : "_9j_4AAQSkZJRgABAQEAYABgAAD__gAyUHJvY2Vzc2VkIEJ5IGVCYXkgd2l0aCBJbWFnZU1hZ2ljaywgejEuMS4wLiB8fEIy_9sAQwAGBAUGBQQGBgUGBwcGCAoQCgoJCQoUDg8MEBcUGBgXFBYWGh0lHxobIxwWFiAsICMmJykqKRkfLTAtKDAlKCko_9sAQwEHBwcKCAoTCgoTKBoWGigoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgo_8AAEQgBdQH0AwEiAAIRAQMRAf_EABwAAAICAwEBAAAAAAAAAAAAAAECAAMEBQYHCP_EAD8QAAE...<cutted_here>",
            "type": "image/jpeg",
            "name":"pic_name.jpg"
        }
    }
]

Notably entry_data became base64_encoded_data, mime_type became just type. Also, I changed the type value to be image/jpeg and added a .jpg extension to the name of the file to be saved. The field names were changed as the API was being stabilized.

This is what I used to try:

  "product": {
    "sku": "randomsku",
    "name": "sku-5550e875431621.27617263",

      },
      {
        "attribute_code": "description",
        "value": "Description"

I've updated the documentation to reflect Bryant's new example.

Hi @bluk and @keharper ,
thank you for supporting and sorry for my late reply .. I spent the whole day to figure it out but now it's time to give it up and ask for your help !

Basically the API call gets executed without issue but I can't see the image associated to the product . .either in the admin or in the frontend .. there is only the product itself with the basic information . For simplify my debugging I have create a json very similar to yours sent yesterday and it doesn't work - here below the json I get back from M2 which make me assume the call has been properly executed :

{"product":{"visibility":4,"attribute_set_id":4,"type_id":"simple","price":"145.0","media_gallery_entries":[{"types":[],"disabled":true,"position":1,"label":"tiny1","content":{"name":"pic1.jpg","type":"image\/jpeg","base64_encoded_data":"your_encoded_data"}},{"types":["image","small_image"],"disabled":false,"position":2,"label":"tiny2","content":{"name":"pic2.jpg","type":"image\/jpeg","base64_encoded_data":"your_encoded_data"}}],"name":"name","extension_attributes":{"stock_item":{"is_in_stock":true,"show_default_notification_message":false,"min_sale_qty":1,"qty":"3","use_config_min_qty":1,"is_qty_decimal":false}},"sku":"261851403821","status":1,"custom_attributes":[{"description","attribute_code":"description"}]}}

Would you recommend to install the beta16 and try with the latest base code ?

Thanks Again!

[bluk]

@naspar You may want to try it with the latest base code. Also, did you look into the store specific view? There's a dropdown to view the store specific information.

[naspar]

Many thanks for your support, this is now working like a charm!
Sorry for my late answer .. I needed to reinstall magento from scratch and try the latest base-code.

The original issue should be fixed already.

[jrosell]

@bluk exactly using your example and I get "There is no MediaGalleryEntryConverter for given type" in magento 2.1 I use.
