PHP/cURL API seems to go wrong?

[4LPH4M3M0RY]

For a project I can only PHP, But for some reason I get the error:
{"code":"BAD_REQUEST","message":"Cannot deserialize instance of java.util.ArrayList out of START_OBJECT token\n at [Source: (io.netty.buffer.ByteBufInputStream); line: 1, column: 171] (through reference chain: com.rarible.protocol.dto.LazyErc721Dto["creators"])","status":400}bool(true) bool(true)

What am I doing wrong? I only use 1 creator so it can't be really a issue with multiple creators (as far as I know).

I have partially fixed it.

Just had to change

            'creators' => [
                "account" => $userToken,
                "value" => 10000
            ],
            'royalties' => [
                "account" => $userToken,
                "value" => 10000
            ],

to:

            'creators' => [
                [
                     "account" => $userToken,
                     "value" => 10000
                ]      
            ],
            'royalties' => [
                [
                    "account" => $userToken,
                     "value" => 10000
                ]
            ],

But yet 1 problem remains, I do not know how to build the signature up.

I currently have:

object(stdClass)#4 (3) {
  ["v"]=>
  int(27)
  ["r"]=>
  string(66) "0x26034351b2d309014edf8b13b35d8afcea47428da856fc078e3a28e60b894e20"
  ["s"]=>
  string(66) "0x3c5280428d1b529e075afc39e8b0805078376ea4dda70f711110cc0116020578"
}

But now I do not know what to do with it...

This is the error it currently gives:

{
  "code": "BAD_REQUEST",
  "message": "Instantiation of [simple type, class com.rarible.protocol.dto.LazyErc721Dto] value failed for JSON property signatures due to missing (therefore NULL) value for creator parameter signatures which is a non-nullable type at [Source: (io.netty.buffer.ByteBufInputStream); line: 1, column: 386] (through reference chain: com.rarible.protocol.dto.LazyErc721Dto[\"signatures\"])",
  "status":400
}
bool(true)

You should follow doc from here: https://ethereum-api.rarible.org/v0.1/doc#tag/nft-lazy-mint-controller
This error tells you that signatures field is missing

@evgenynacu Thank you, that is fixed now.

But how can I make/construct a signature with the provided signature object?

[evgenynacu]

You should construct message and sign it according to eip-712. We don't use phone so I don't know if there is a lib for that. Also, usually this happens on the frontend.
