{% tabs %}
{% tab title="🌮 Taquito" %}

```javascript
const dexCoreAddress = "KT1...";
const parmas = {
    pair_id: 0,
    min_token_a_out: 100,
    min_token_b_out: 100,
    shares: 100,
    liquidity_receiver: "tz1.../KT1...",
    candidate: "tz1...",
    deadline: String(Date.parse((await tezos.rpc.getBlockHeader()).timestamp) / 1000 + 100),
};
const dexCore = await tezos.contract.at(dexCoreAddress);
const operation = await dexCore.methodsObject.divest_liquidity(parmas).send();

await operation.confirmation();
```

{% endtab %}
{% endtabs %}

### Errors

* `108` - pair (pool) with the specified `token_id` not listed.
* `109` - pair doesn't have a liquidity.
* `114` - insufficient liquidity.
* `115` - dust output (zero tokens amount expected).
* `116` - high expectations of output tokens.
* `136` - reentrancy.
* `142` - wrong reserves state after execution of the operation.
* `144` - action outdated (the time until which the transaction remained valid was passed).
* `412` - non payable entrypoint (can't accept TEZ tokens during call of an entrypoint).
