<p dir="auto">I am attempting to get Firebase, specifically Firestore, working with Deno but am running into issues. I've raised this as a <a href="https://stackoverflow.com/questions/70564143/using-firsebase-firestore-with-deno" rel="nofollow">question on StackOverflow</a>.</p>
<p dir="auto">These issues seem to be with the compatiblity between the <code class="notranslate">firebase</code> module and Deno, as the error even occurs in the <a href="https://deno.com/deploy/docs/tutorial-firebase" rel="nofollow">Deno Firebase tutorial</a>, and if running the <a href="https://deno.com/examples/firebase.js" rel="nofollow">source code</a> directly with <code class="notranslate">deno run --allow-net https://deno.com/examples/firebase.js</code>.</p>
<p dir="auto">When utillizing the code and following the tutorial at: <a href="https://deno.com/deploy/docs/tutorial-firebase/" rel="nofollow">https://deno.com/deploy/docs/tutorial-firebase/</a><br>
On first visit, the deploy fails.</p>
