Problems while importing json with matrix data

[Humbi1992]

Description

I'm having problems importing my json file which contains matrix fields.

Steps to reproduce

1. Create an JSON File with following content:

...
"Benefits": [
    {
        "Shortcut Title": "Shortcut Title",
        "Full Title": "Title",
        "Arguments": {
            "Argument Elements": [
                {
                    "Subtitle": "Subtitle",
                    "Paragraph": "This is a paragraph",
                    "Picture": "image01.png",
                    "Picture Alt Text": "This is Image 01"
                },
                {
                   "Subtitle": "Subtitle",
                    "Paragraph": "This is a paragraph",
                    "Picture": "image02.png",
                    "Picture Alt Text": "This is Image 02"
                }
            ]
        }
    }
],
...

2. Map:

• Argument: Subtitlearguments[argument][subtitle] | <Benefits/Arguments/Argument Elements/Subtitle>
• Argument: Paragrapharguments[argument][paragraph] | <Benefits/Arguments/Argument Elements/Paragraph>
• Argument: Picturearguments[argument][picture] | <Benefits/Arguments/Argument Elements/Picture>
• Argument: Picture Alt Textarguments[argument][pictureAltText] | <Benefits/Arguments/Argument Elements/Picture Alt Text>

3. Execude Feed
4. It will ignore arguments array

Hi, thanks for getting in touch!

Can you please let me know what you have selected as the “Primary Element” on the second screen when setting up a feed (a screenshot would be nice)?

Also, just so that we’re on the same page, is your matrix field called “Arguments” and has a block type called “argument”, and the block has a “subtitle” field (e.g. plain text), “paragraph” field (e.g. plain or rich text) and “picture” Assets field and the volume for it has “picture alt text” field in its field layout - is that correct?

Hello @i-just

I collected the following information for you:

My Field Structure:

Benefits (SuperTable) -- Arguments (Matrix) ---- Argument (Matrix Element)

As first item i selected products, like in the Screenshot below:

Thanks for the additional info. After running your feed, do you see any errors in the Logs tab (or in the storage/logs/feedme.log file)?

@i-just

Here the feedme.log after the import:

feedme.log

Unfortunately, no real indication of an error or similar.

I tried to reformat the JSON into this:

"Benefits": [
        {
          "Full Title": "",
          "Shortcut Title": "",
          "Arguments": [
            {
              "Subtitle": "",
              "Paragraph": "",
              "Image": ""
            },
         ....

But still doesn't work for me.

Ok, so Feed Me doesn’t support nested Matrix + Super Table (more info can be found, e.g. here: https://github.com/craftcms/feed-me/issues/771). That said, this usually results in a telltale error: Call to a member function getBlockTypeFields() on null - Matrix.php, which is what I’m getting in my tests and why I asked if you saw any after the feed is run.

Can you send the composer.lock, composer.json, database export and a JSON feed file (with just one full element) to [email protected] so I can try to replicate this and dig deeper?
