title: Cloud Functions for Firebase - deploy error - Failed to initialize a region?
body: <p>I'm in the process of uploading some Cloud Functions for Firebase via the Firebase CLI. I have my <code>functions</code> folder setup and everything is correct. :I actually use this exact functions folder in another project but for whatever reason in this particular project, when I run <code>firebase deploy --only functions</code>, I get this:</p>
  
  <pre><code>i  deploying functions
  i  functions: ensuring necessary APIs are enabled...
  i  runtimeconfig: ensuring necessary APIs are enabled...
  ✔  runtimeconfig: all necessary APIs are enabled
  ✔  functions: all necessary APIs are enabled
  i  functions: preparing functions directory for uploading...
  i  functions: packaged functions (972 B) for uploading
  ✔  functions: functions folder uploaded successfully
  i  starting release process (may take several minutes)...
  i  functions: updating function getUserByEmail...
  ⚠  functions[getUserByEmail]: Deploy Error: Failed to initialize a region
  
  
  Functions deploy had errors. To continue deploying other features (such as database), run:
      firebase deploy --except functions
  
  Error: Functions did not deploy properly.
  </code></pre>
  
  <p>Does anyone know what this error means?</p>
  
  <p>Thanks in advance!</p>
