title: Firebase cloud function deploy error
body: <p>irregularly my firebase deployment get stuck at this log: </p>
  
  <pre><code>i  functions: updating function [FUNCTION NAME]...
  </code></pre>
  
  <p>After canceling the deploy and retrying it throws the following error message: </p>
  
  <pre><code>⚠  functions: failed to update function resetBadgeCount
  ⚠  functions: HTTP Error: 400, An operation on function [FUNCTION NAME] 
  in region us-central1 in project [PROJECT NAME] is already in progress. 
  Please try again later.
  </code></pre>
  
  <p>So it seams like that the deploy got stuck and kept in the pipeline blocking further deploys. After a while it let me deploy the functions normally again.
  But is there an explanation for this? Or maybe even a word around?</p>
