Permission denied during gcloud app deploy using Google Cloud SDK : <p>It is insanely hard, to deploy an app to Google App Engine, using Google Cloud SDK.</p>

<p>I had tried the below 2 commands</p>

<pre><code>C:\Users\yccheok\Desktop\jstock-android-appengine&gt;gcloud config set project jstock-android
Updated property [core/project].

<p>Then, I went through <a href="https://cloud.google.com/appengine/docs/admin-api/accessing-the-api" rel="noreferrer">https://cloud.google.com/appengine/docs/admin-api/accessing-the-api</a> , it mentioned I need to use <strong>Admin API</strong>. So, I do it step by step carefully.</p>

<h2>Step 1</h2>

<p><a href="https://i.stack.imgur.com/dRVVB.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dRVVB.png" alt="enter image description here"></a></p>

<h2>Step 2</h2>

<p><a href="https://i.stack.imgur.com/LOm7K.png" rel="noreferrer"><img src="https://i.stack.imgur.com/LOm7K.png" alt="enter image description here"></a></p>

<p>It mentions <strong>Admin API</strong> is enabled. Now I need credential.</p>

<h2>Step 3</h2>

<p><a href="https://i.stack.imgur.com/MuhA6.png" rel="noreferrer"><img src="https://i.stack.imgur.com/MuhA6.png" alt="enter image description here"></a></p>

<h2>Step 4</h2>

<p><a href="https://i.stack.imgur.com/6QUpo.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6QUpo.png" alt="enter image description here"></a></p>

<p>OK. Now they mention I don't need create new credential. I can use <strong>Application Default Credentials</strong> ?!</p>

<h2>Step 5</h2>

<p>So, I went to <a href="https://developers.google.com/identity/protocols/application-default-credentials?hl=en_GB" rel="noreferrer">https://developers.google.com/identity/protocols/application-default-credentials?hl=en_GB</a> . I learn that I need to run</p>

Application Default Credentials.

<h2>Step 6</h2>

<p><a href="https://i.stack.imgur.com/TJsIP.png" rel="noreferrer"><img src="https://i.stack.imgur.com/TJsIP.png" alt="enter image description here"></a></p>

<h2>Step 7</h2>

<p><a href="https://i.stack.imgur.com/cNo3x.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cNo3x.png" alt="enter image description here"></a></p>

<hr>

<p>Still, after completing the above 7 steps, I still get the exact same error message, when trying to run</p>

<pre><code>gcloud app deploy app.yaml --log-http --verbosity=debug
</code></pre>

<p>Can anyone let me know, what step I'm still require, in order to deploy my Python app to Google App Engine, using Google Cloud SDK?</p>
