"Laravel 10 - API key not recognized in .env file"

<p>I'm using <code>Laravel Framework 10.15.0</code>. </p>
<p>I tried loading my API key in the following way: </p>
<pre class="brush:php;toolbar:false;">$apiKeyOpenAI = env('OPENAI_API_KEY');
$client = OpenAI::client($apiKeyOpenAI);</pre>
<p>In my <code>.env</code> file, the API key is clearly defined: </p>
<p><code>OPENAI_API_KEY=xx-xxxxxxxxxxxxxxxxxxxxxxx</code></p>
<p>However, when executing my application on the server, I get that <code>$apiKeyOpenAI</code> is null. </p>
<p>However, I do have OPENAI_API_KEY in my <code>.env</code> file.I've checked it! </p>
<p>I tried clearing the cache <code>php artisan config:clear </code> but I still get the error: </p>
<pre class="brush:php;toolbar:false;">TypeError
OpenAI::client(): Argument #1 ($apiKey) must be of type string, null given, called in /var/www/demo-website/app/Console/Commands/AdminCommand.php on line 151

<p>Any suggestions what I'm doing wrong? </p>
<p>Thanks for your reply! </p>
<p><strong>Update</strong></p>
<p>After deploying to the server, I need to run this script to make it work: </p>
<pre class="brush:php;toolbar:false;">Route::get('/clear', function() {
Artisan::call('cache:clear');
Artisan::call('config:clear');
return "Cache, Config is cleared";
})->middleware(['auth', 'admin']);</pre>
<p>On deployment, this script will also run automatically: </p>
<pre class="brush:php;toolbar:false;">#!/bin/sh
set -e

Do not use
env()outside ofconfig/*.phpfiles. If you ever runphp artisan config:cache(which should usually be done in a production environment) thenenv()will stop working outside of these files (for most cases says; theenvkey can still be loaded, but this is not typical for most Laravel setups). This is why you need to runphp artisan config:clearso thatenv()does not returnnull.Add a key in
config/app.php(or any other file in theconfig/directory):'open_ai_api_key' => env('OPENAI_API_KEY', null)Then, when you want to use this key, use
config()Helper function:$apiKeyOpenAI = config('app.open_ai_api_key'); $client = OpenAI::client($apiKeyOpenAI);Note:
appis the file name,open_ai_api_keyis the array index. If you use a different file, such asconfig/services.php, then you should useconfig('services.open_ai_api_key')Please refer to the documentation for details:
