json_decode is not working properly in magento 2.4.0

Question

I am trying to decode the JSON in normal string and print that in the info log in Magento 2.4.0 but I am getting nothing in the info log. Adding the code below anyone please suggest a solution for this.

Code I am using

public function execute()
{
    $result = $this->resultJsonFactory->create();
    $isSuccess = $this->tracking->createApi();
    $jsonresponse = json_decode($isSuccess); // decoding here
    $this->logger->info(var_dump($jsonresponse)); // trying to print in info log
    return $result->setData(['success' => $isSuccess]);
}

$isSuccess - this variable has the below JSON data

Coveolog.INFO: {"sourceType":"PUSH","id":"dsspartnersorggrc3y48w-uk7awlmkozpufpe6pwaeoycmpy","name":"DSS-Coveo_M2-Integration-B2C-product-en_US","sourceVisibility":"SHARED","customParameters":{},"information":{"sourceStatus":{"type":"CREATING","timestamp":1617776580670,"allowedOperations":["DELETE"]},"numberOfDocuments":0,"documentsTotalSize":0},"pushEnabled":true,"onPremisesEnabled":false,"streamEnabled":false,"logicalIndex":"default","preConversionExtensions":[],"postConversionExtensions":[],"permissions":{"permissionLevels":[{"name":"Source Specified Permissions","permissionSets":[{"name":"Shared","permissions":[{"allowed":true,"identityType":"GROUP","identity":"@","securityProvider":"Email Security Provider"}]}]}]},"urlFilters":[{"filter":"*","includeFilter":true,"filterType":"WILDCARD"}],"ocrFileTypes":[],"resourceId":"dsspartnersorggrc3y48w-uk7awlmkozpufpe6pwaeoycmpy"} [] []

1. You don't need to use var_dump() when logging something in a file; the function is used when you want to dump info on the browser instead.
2. When decoding, I would suggest you use the function like this json_decode($isSuccess, true) so that your variable's content is properly converted to associative array and not object.
