    ]
}

The API returns:

{
    "message": "500: Internal Server Error",
    "code": 0
}

This limit is not documented and the error response is not informative.

This issue also persists despite the media type being used. The 64 limitation appears to include all elements of Media Gallery and Thumbnail

Steps to Reproduce

Send a Components V2 message with 65 or more media components (fishes are optional)

Expected Behavior

The API should send a clear error with a documented limitation on media components and error code, or allow the sending of >64 media components

Current Behavior

The api returns a 500 error when sending >64 media components

No response

Confirming I'm also experiencing this issue with Components V2.

When attempting to send 64 or more media components, the API returns a 500 Internal Server Error, exactly as described.

My specific use case involves trying to send exactly 65 images (of cows, importantly!) to a group chat ("the boys chat"), and I'm consistently hitting this error when the count exceeds 64.

Hoping for a fix soon!

[OoLunar]

I can confirm this limitation also affects my attempt to send 128 penguin pictures (🐧 x128) via Components V2. The behavior is identical to both the fish and cow cases mentioned above:

• 64 penguins: Works perfectly
• 128 penguins: Returns 500: Internal Server Error

This appears to be a hard limit affecting all media types, whether fish, cows, or penguins. The undocumented 64-item restriction makes it impossible to properly fill empty channels with adequate amounts of aquatic birds (or other media).

Would love to see either:

• The limit raised (128 would be ideal for my penguin needs)
• Proper documentation of the limitation
• A more descriptive error message

Until then, my penguin campaign remains grounded. 🐧✈️

[Naamloos]

+1 on this limitation. As a particularly hungry individual, I can easily consume a large amount of food- in fact, up to 128 hamburgers in one sitting (for those unfamiliar, they look like this: 🍔). Increasing the limit to 128 media items would significantly help accommodate my unusual appetite.

Currently, the restriction to 64 items means I can only receive half of what I need at a time, which is inconvenient and frustrating. If I had known beforehand, I could have accommodated my needs more properly.

I agree with @OoLunar's earlier points: if raising the limit isn't an option, please at least document this behavior clearly.

[Lulalaby]

tl;dr the request entity is too large.

The correct error to return would be 40005

You can see that 100 items are possible when sending something invalid like https://a.tld/a

Also since when are issues part of shitpost places

[Naamloos]

It's just some lighthearted fun, sorry if it made you uncomfortable.

Anyway, I do agree that, even for other validation issues, better error reporting from the API might be nice. Plus the fact that this error is seemingly undocumented.

It seems this may be the case.

When attempting to send 1x1 pixels https://upload.wikimedia.org/wikipedia/commons/c/ca/1x1.png, I can reach 66 pixels without issue, but 67 pixels returns:

{
    "message": "500: Internal Server Error",
    "code": 0
}

The fish vs pixel deviation suggests this error may be coming from Discord's backend - at some point - processing all of the image data and returning some form of error related to message size limitations.

With 66 1 pixel images, across 7 media galleries, and 83 characters in a text display component, the response is also:

{
    "message": "500: Internal Server Error",
    "code": 0
}

Further suggesting this is due to the request entity being too large to process.

The largest response body I was able to achieve was 31.08 KB uncompressed & 1.16 KB
compressed, with the request body at 15.11 KB.

I thought the nature of this issue was rather fishy, hopefully we've reeled in the source of this issue & this uncaught error.

[gabemeola]

Thanks for the report. You may be hitting a payload dl limit with fish and mammals. Maybe try a smaller more compact species like a gecko lizard. Issue is synced and will get back to y'all on this.

[Pavel-Boyazov]

I think it's the same situation as in #7448

[DV8FromTheWorld]

When attempting to send 1x1 pixels https://upload.wikimedia.org/wikipedia/commons/c/ca/1x1.png, I can reach 66 pixels without issue, but 67 pixels returns:

In this case it has nothing to do with the size of the image. It entirely has to do with the size of the content in the JSON.
We'll put a limit in here that produces a reasonable 400.

Also, why y'all gotta make more work for me 😿

[OoLunar]

We all say "thank you DV8" in complete unison
