Let's decode the hex values

version
"ethers/5.7.1"
provider.network.name
"homestead"
ethers.utils.arrayify("0x8fa5870d64b323b53913cbf6a1ee5f80beab16f333b742c881554f931fe867a0");
Uint8Array { 143, 165, 135, 13, 100, 179, 35, 181, 57, 19, 203, 246, 161, 238, 95, 128, 190, 171, 22, 243, 51, 183, 66, 200, 129, 85, 79, 147, 31, 232, 103, 160 }

They seem to match

// Decoded values
const d1 = [ 143, 165, 135, 13, 100, 179, 35, 181, 57, 19, 203, 246, 161, 238, 95, 128, 190, 171, 22, 243, 51, 183, 66, 200, 129, 85, 79, 147, 31, 232, 103, 160 ];
const d2 = [ 104, 74, 233, 91, 17, 153, 29, 224, 138, 40, 72, 221, 19, 140, 105, 40 ];

// Original values
const o1 =[
      143, 165, 135,  13, 100, 179,  35, 181,
       57,  19, 203, 246, 161, 238,  95, 128,
      190, 171,  22, 243,  51, 183,  66, 200,
      129,  85,  79, 147,  31, 232, 103, 160
    ];
const o2 = [
      104,  74, 233, 91, 17, 153,
       29, 224, 138, 40, 72, 221,
       19, 140, 105, 40
    ];
    
function arrayEquals(a, b) {
    return Array.isArray(a) &&
        Array.isArray(b) &&
        a.length === b.length &&
        a.every((val, index) => val === b[index]);
}

console.log(arrayEquals(d1, o1)); // true
console.log(arrayEquals(d2, o2)); // true

Okay, so the inputs match, why does the contract throw then?

The demo doesn't throw

// Outputs from taco-demo
const dd1 = [143, 165, 135, 13, 100, 179, 35, 181, 57, 19, 203, 246, 161, 238, 95, 128, 190, 171, 22, 243, 51, 183, 66, 200, 129, 85, 79, 147, 31, 232, 103, 160];
const dd2 = [104, 74, 233, 91, 17, 153, 29, 224, 138, 40, 72, 221, 19, 140, 105, 40];

console.log(arrayEquals(dd1, o1)); // true
console.log(arrayEquals(dd2, o2)); // true
