Int type uses LE as default in the toHex

[zjb0807]

isLe = false should be isLe = true here. totalIssuance.toHex() returns big-endian encoding by default, which will differ from what u8aToHex returns.

	public toHex (isLe = false): HexString {
	// For display/JSON, this is BE, for compare, use isLe
	return bnToHex(this, {
	bitLength: this.bitLength(),
	isLe,
	isNegative: !this.isUnsigned
	});

If the storage is defined as eraReward(u32): u128， to the data by entriesPaged, it is not the real storage key and value.

console.log(`${key.toHex()},${value.toHex()}`);
