Error "Undefined array key "coders""

[bjutkoski]

I'm having this error Undefined array key "coders" when methods has tuple[] or tuple as input/output

/web3p/web3.php/src/Contracts/Types/Tuple.php:116

input as tuple[]

{
"inputs": [
{
"internalType": "string",
"name": "documentId",
"type": "string"
},
{
"components": [

tuple as output

i am encountering the same issue now

I have same issue while reading tuple data output

I have modified Ethabi class decodeParameters function as given below and its working fine:

public function decodeParameters($types, $param)
{
if (!is_string($param)) {
throw new InvalidArgumentException('The param must be string.');
}

    // change json to array
    $outputTypes = [];
    if ($types instanceof stdClass && isset($types->outputs)) {
        $types = Utils::jsonToArray($types, 2);
    }
    if (is_array($types) && isset($types['outputs'])) {
        $outputTypes = $types;
        $types = [];
        if(!empty($outputTypes['outputs'][0]['components']))
        {
            foreach ($outputTypes['outputs'][0]['components'] as $component) {
                $types[] = $component['type'];
            }
        }
        else{
            foreach ($outputTypes['outputs'] as $output) {

                }
            }
        }
    }
    $typesLength = count($types);
    $abiTypes = $this->parseAbiTypes($types);

    // decode with tuple type
    $results = [];
    $decodeResults = $this->types['tuple']->decode(Utils::stripZero($param), 0, [ 'coders' => $abiTypes ]);
    for ($i = 0; $i < $typesLength; $i++) {

            if (isset($outputTypes['outputs'][0]['components'][$i]['name']) && empty($outputTypes['outputs'][0]['components'][$i]['name']) === false) {
