How to use the @0x/assert.assert.isWebUri function in @0x/assert

constructor(url: string) {
        assert.isWebUri('url', url);
        this._apiEndpointUrl = url.replace(TRAILING_SLASHES_REGEX, ''); // remove trailing slashes
    }
    /**

export const checkErc20TokenLiquidityAsync = async (sraApiUrl: string, erc20TokenAddress: string) => {
    assert.isWebUri('sraApiUrl', sraApiUrl);
    assert.isETHAddressHex('erc20TokenAddress', erc20TokenAddress);

    const tokenAssetData = assetDataUtils.encodeERC20AssetData(erc20TokenAddress);
    const httpClient = new HttpClient(sraApiUrl);
    const response = await httpClient.getAssetPairsAsync({
        networkId: Network.Mainnet,
        assetDataA: MAINNET_WETH_ASSET_DATA,
        assetDataB: tokenAssetData,
        perPage: 1000,
    });
    const supported = response.records.length > 0;
    return { supported };
};
