Images posted via the API embed as empty, do not display.

[AshGlidewell]

Hey there, started a new discussion instead of piggybacking off of someone else's question which doesn't seem to be entirely the same thing. I'm encountering a problem when sending posts with embeds and uploading blobs.

I've attached a few files.

This is the full payload of the image in Base64 along with the image

ImagePayload.txt

This is the JSON that I get back after uploading said image

{"blob":{"$type":"blob","ref":{"$link":"bafkreigfo6s7ajzqk4gpw3ntubmkcealhsw633jrpn2j3ak6tcqaw4bu4e"},"mimeType":"image/png","size":179595}}

This is the JSON that I send back to create the post with an embed:

{
    "collection": "app.bsky.feed.post",
    "repo": "did:plc:7yovtpsbz3jfyzde2pjmkuig",
    "record": {
        "text": "This week's #VNDev discussion! What techniques do you use to make sure your visual novel's dialogue flows smoothly?",
        "createdAt": "2023-12-11T18:30:18.5800230Z",
        "type": "app.bsky.feed.post"
    , "embed":{ "$type": "app.bsky.embed.images", "images": [ {"alt": "This week's #VNDev discussion! What techniques do you use to make sure your visual novel's dialogue flows smoothly?", "image":{ "$type": "blob", "ref": {"$link": "bafkreigfo6s7ajzqk4gpw3ntubmkcealhsw633jrpn2j3ak6tcqaw4bu4e"},  "mimeType": "image/png","size":179595}}]
}}}

This is the response I get back after sending that:

{"uri":"at://did:plc:7yovtpsbz3jfyzde2pjmkuig/app.bsky.feed.post/3kgc2k5zibc2a","cid":"bafyreihcl5if2j4dcsnfwl62puqnie2cgfqd6eaihc3atmgewiedgqq44i"}

What I'm trying to do is upload an image with a small body of text as the alt text, then embed that into a post.

I'm using the example I found here as a guide to making my own.

Here is a post containing the result of the above:

I would hope that I would get an error if I'm submitting something incorrectly along the way, but this doesn't produce any errors, but it's also not working the way I expect it to. Any help would be appreciated.

You need to upload the image as raw data, not as a base64 string.

Oh my lord, I knew it was something stupid. Thanks, that was exactly what it was.

Thank you for highlighting this! Based on the docs it might appear that blob upload should be base64. I just tested with raw data and works fine.
