Guzzle post json data causing 400 bad request - php

Question

I am trying to use guzzle to do a post request to an open API. I am also sending the post data as follows. For some reason i am getting a 400 bad request
$req = $client->request('POST',$this->base_url.'nutrients?app_id='.$this->app_id.'&app_key='.$this->api_key,[
'headers' => [
'Content-Type' => 'application/json'
],
\GuzzleHttp\RequestOptions::JSON => [
"yield" => $portions,
"ingredients" => [
"quantity" => $portions,
"measureURI" => "\"$f_uri\"",
"foodURI" => "\"$m_uri\""
]
]
]);
$response = $client->send($req);
$decoded = json_decode($response->getBody());
dd($decoded);
The api documentation shows the method in curl as follows:
curl call:
curl -d #food.json -H "Content-Type: application/json" "https://api.edamam.com/api/food-database/nutrients?app_id=${YOUR_APP_ID}&app_key=${YOUR_APP_KEY}"
food.json:
{
"yield": 1,
"ingredients": [
{
"quantity": 1,
"measureURI": "http://www.edamam.com/ontologies/edamam.owl#Measure_unit",
"foodURI": "http://www.edamam.com/ontologies/edamam.owl#Food_11529"
}
]
}
My links for measureURI and foodURI are generated correctly.

You don't need to do ->send() after the ->request(), it already returns an instance of ResponseInterface.
So just
$response = $client->request('POST', $this->base_url.'nutrients?app_id='.$this->app_id.'&app_key='.$this->api_key, [
// ...
]
]);
$decoded = json_decode($response->getBody()->getContents());
