	// Todo: metadataSize is hardcoded at this moment but should be caliculated in the future.
	// On 8.July.2022, Metadata.getMinimumBalanceForRentExemption is returning wrong price.
	// const metadataFee = await Metadata.getMinimumBalanceForRentExemption(
	// {
	// key: Key.MetadataV1,
	// updateAuthority: mintAuthority,
	// mint: form.mintAccount?.pubkey,
	// data: tokenMetadata,
	// primarySaleHappened: true,
	// isMutable: true,
	// tokenStandard: TokenStandard.Fungible,
	// uses: null,
	// collection: null,
	// editionNonce: 255,
	// },
	// connection.current
	// )
	const metadataFee = await connection.current.getMinimumBalanceForRentExemption(
	679
	)

Metadata.getMinimumBalanceForRentExemption is still returning wrong price on 22.July.2022.
I also tried to make Buffer with the params and get length from that but it doesn't have enough length as actual on chain data.

It looks like we need to submit a script to the Metaplex team to reproduce this error and resolve it jointly.
