Calling a payable method with correct ABI throws "Error: Can not send value to non-payable contract method or constructor"

[tricdc]

I am trying to call releaseFunds():

    function releaseFunds() payable public{
        require(msg.sender == buyer || msg.sender == seller);
        require(msg.value == getOraclizePrice());
        require(paidFor);
        bytes32 id = oraclize_query("URL", [my query url], gasLimit);
        callbacks[id] = 0x04;
    }
    
    function releaseFunds_callback(string result) private{
        if(bytes(result).length == 0){}
        else status = byte(bytes32(stringToBytes32(result)));
        if(status == 0x34){
            uint256 amountToTransfer = price;
            price = 0;
            seller.transfer(amountToTransfer);
            emit FundsReleased();
        }
    }
    
    function __callback(bytes32 myid, string result) public{
        require(msg.sender == oraclize_cbAddress());
        if(callbacks[myid] == 0x01) addTrackingNumber_callback(result);
        else if(callbacks[myid] == 0x02) buyerCancel_callback(result);
        else if(callbacks[myid] == 0x03) updateTracking_callback(result);
        else if(callbacks[myid] == 0x04) releaseFunds_callback(result);
    }

My ABI:

	{
		"constant": false,
		"inputs": [],
		"name": "releaseFunds",
		"outputs": [],
		"payable": true,
		"stateMutability": "payable",
		"type": "function"
	}

Here's the Javascript code:

        contract.methods.releaseFunds().send({
            from: accounts[0],
            value: oraclizeFee
        })
        .on('error', function(error){
            setProgressBar("error");
        })
        .on('transactionHash', function(txHash){
            transactionHash = txHash;
            setProgressBar("half");
        })
        .on('confirmation', function(confirmationNumber, receipt){
            setProgressBar("full");
            statusText.innerText = "Transaction complete.";
        });

The error I get:

Uncaught (in promise) Error: Can not send value to non-payable contract method or constructor
    at Object.d._executeMethod (web3.min.js:1)
    at <anonymous>:1:41

I am using MetaMask as my Web3 provider on x64 Windows 10 in Google Chrome. This is on the Kovan testnet.

When I call the same method in Remix, the transaction goes through just fine.
