[Blocks API Error]

[mgpai22]

When /blocks/headerIds is posted with a huge amount of header ids, it works sometimes but frequently I have come across this error.

{
    "error": 400,
    "reason": "bad.request",
    "detail": "The request content was malformed:\nAttempt to decode value on failed cursor: DownField(header)"
}

I think the issue is either requesting too much data at once or due to spamming the node. It could be a combination of this too.

Here is the data I queried, it is 50 header ids
