Can't lazymint to rarible with more than 1 supply

I am using the rarible plugin, and am setting all the right params (I think), but no matter what, it won’t make more than 1 of 1.

let res = await Moralis.Plugins.rarible.lazyMint({
            chain: 'rinkeby',
            userAddress: user.get('ethAddress'),
            tokenType: 'ERC721',
            listAssetClass: 'ETH',
            supply: parseInt(,
            listTokenAmount: parseInt(,
            listTokenValue: (10 ** 18) * parseFloat(form.value),
            list: true,
            tokenUri: 'ipfs://' + metadataHash,
            royaltiesAmount: 100, // 0.05% royalty. Optional

Thanks for any insight.
