Nft-lazy-mint-controller requiers a signature. How do I get it?

It looks like nft-lazy-mint-controller requires a signature (string)
How to get it? Does anybody know?

Eugene Nacu | Rarible#9332:

Pls, check example from the docs. There is an example how to get the signature and lazy mint.

It's done using sdk

kastersky#7478:

I tried that. SDK seems not to be working. So I'm looking for other ways to make it work

Here's what the sdk mint post request returns: 400. The part that makes no sense is that the request payload has no signatures.

I think "generate token ID" returns a signature.

{
    "tokenId": "6",
    "signature": {
        "v": 27,
        "r": "0x95584c3108dace46549e0d6ac7ac1c9d25ccc91028210fe0dd335efd2f9396f5",
        "s": "0x0d6dec6ffe5f39b67b3268c868dc61ff3af87bea9cab89d8fc55265bb363a40e"
    }
}

Right now it's an object. Can you please help me understand how to convert it to a string that is needed for minting?

Eugene Nacu | Rarible#9332:

What doesn't work? Did you check an example? https://github.com/rarible/protocol-example

kastersky#7478:

I did. It returns 400, my guess is that SDK can't find a signature. The image is attached above. That's why I'm trying to find a way to get the signature manually and bypass the SDK. Is there a way to get the signature without the SDK? I used "generate token ID", Is it the way to go?

if so, how do i turn this "signature": {
"v": 27,
"r": "0x95584c3108dace46549e0d6ac7ac1c9d25ccc91028210fe0dd335efd2f9396f5",
"s": "0x0d6dec6ffe5f39b67b3268c868dc61ff3af87bea9cab89d8fc55265bb363a40e"
}

into an acceptible signature string for the mint request on your API?
