Inability to check if utxo belongs to an address

[Fiftyw3bs]

I've been struggling with a very weird phenomenon.

I have a validator, whose UTXO I'm trying to spend/pay to the invoking wallet address.

Mesh is being used for building the transaction, while the validator is written in aiken.

There is a function that's suppose to check if a certain amount is being paid to an address, but my validator keeps failing unless I omit the address comparison expression:

pub fn value_paid_to_address(
  policy_id: PolicyId,
  name: AssetName,
  value: Int,
  addr: Address,
  outputs: List<Output>,
) -> Bool {
  outputs
    |> list.any(
        fn(output) { quantity_of(output.value, policy_id, name) == value && output.address == addr},
      )
}

Removing output.address == addr works.

An excerpt of the transaction is as follows, which clearly shows that the value is being paid to the address:

{
    ...
    "outputs": [
        {
            "address": "addr_test1qpywx....hw64n788msj4ugzgag2sjg7h48us77k3p4kgc7sutsa7gdk56hcqqlqhrlnw6lxsh4dp4a",
            "amount": [
                {
                    "unit": "29e18c9c2b4a0350aed8069...60a0ac1808a7453485348",
                    "quantity": "1"
                }
            ],
            "datum": null,
            "referenceScript": null
        }
    ],
    ...
}

Has anyone ever encountered such issue? Any assistance rendered would be greatly appreciated.
