Malformed Response Exception

[redalys]

I am using version 5.4 of gocardless pro and it does not work for me, the library always returns that error, example:

$access_token = 'my_production_token';
$client = new \GoCardlessPro\Client(array(
'access_token' => $access_token,
'environment' => \GoCardlessPro\Environment::LIVE
));

$client->billingRequestFlows()->create([
"params" => [
"redirect_uri" => "https://my-company.com/landing",
"exit_uri" => "https://my-company.com/exit",
"prefilled_customer" => [
"given_name" => "Frank",
"family_name" => "Osborne",
"email" => "frank.osborne@acmeplc.com"
],
"links" => [
"billing_request" => "BRQ123"
]
]
]);
