My array have only 3 elements, but I indexed it with an modulo operation (%) that use a uint128_t value. The result of modulo operation is a uint128_t value type.
But well, I now use with success a standard cast for obtain a valid index type value! Thanks!

But I would rather question the wisdom of using a multiprecision type in that context?
