Feedme always adds empty Matrix block

[JayBox325]

Description

I have generated a JSON file and formatted some test Matrix blocks like this:

"pageComponents": {
    "MatrixBlock": [
        { 
            "body": "<p>Test paragraph 123456.</p><p>[IMAGE BLOCK - test.jpg]</p>" 
        },
        {
            "body": "<p>This is a test paragraph, too.</p>" 
        }
    ]
}, 

Yet, when I complete the import, it's always creating rogue empty matrix blocks, even though there's nothing in the JSON to tell it to do that. I think our next port of call is to write a JS import function using GraphQL Mutations but we'd like to keep using FeedMe if possible. See here there's always an empty block:

Steps to reproduce

1. Create json to import with matrix blocks
2. Import it
3. See empty block

Hi, thanks for getting in touch. I’m not able to reproduce that using the feed snippet you provided. Could you please confirm the Craft CMS and Feed Me versions? Could you also please share a screenshot of the mapping screen?

Thanks for the extra info. I was able to reproduce and raised a PR for this.

[JayBox325]

Thanks very much. It was quite a relief to see you encountered it too! I have spent days trying to figure out how to resolve it and thought I was going mad 😅

[JayBox325]

Hi @i-just is there a schedule for the release?

[i-just]

There’s no ETA, sorry, but we’ll try to get a new release out soon.

[angrybrad]

Fixed in #1613 and will be included in the next 5.x and 6.x releases!
