Ok, here is what I found. 

According to this page: <a href="https://cloud.google.com/functions/docs/securing/managing-access-iam#allowing_unauthenticated_function_invocation" rel="noreferrer">https://cloud.google.com/functions/docs/securing/managing-access-iam#allowing_unauthenticated_function_invocation</a>

<blockquote>
 As of January 15, 2020, HTTP functions require authentication by
 default. You can specify whether a function allows unauthenticated
 invocation at or after deployment.
</blockquote>

Here is what you do:

1- Browse to the link above

2- Find "Viewing users" section and click on the "Go to Google Cloud Console" button.

<a href="https://i.stack.imgur.com/B1K3w.png" rel="noreferrer"><img src="https://i.stack.imgur.com/B1K3w.png" alt="enter image description here"></a>

3- On the screen that opens, you will see a list of your deployed cloud functions. 
Select the one that is throwing the UNAUTHENTICATED error.

Click the Add Member button that appears on the right pane.

<a href="https://i.stack.imgur.com/Or9mv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Or9mv.png" alt="enter image description here"></a>

4- Select Cloud Functions Invoker role

<a href="https://i.stack.imgur.com/Rkt5u.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Rkt5u.png" alt="enter image description here"></a>

5- Type allusers inside the "New Members" box. Select allUsers or allAuthenticatedUsers (Try with both to see which one works for you)

<a href="https://i.stack.imgur.com/JWLj9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/JWLj9.png" alt="enter image description here"></a>

6- Hit "Save"

You should be able to invoke your firebase https callable cloud function now, and the UNAUTHENTICATED error should be gone.

blocks|key|3930748|text|在我的例子中，我在自己的应用程序中写错了函数名。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3930749|final+callable+=+_functions.httpsCallable('wrong+function+name+in+here');|code-block|syntax|javascript|3930750|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

in my case, I write wrong function name in my Flutter app

blocks|key|3930827|text|我也遇到了同样的问题，对我起作用的是更改文件中函数的名称(当然也是调用函数的位置)并重新部署它，这会自动删除第一个函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3930828|编辑1:我刚刚又遇到了同样的问题，这次我没有重命名这个函数。我只在防火墙中手动删除了该功能，然后重新部署了它。这也很管用。|3930829|编辑2:我又一次遇到了同样的问题。然而，这一次我无法用上面的选择来修复它。我升级了我的防火墙工具，这个新版本(10.3.1)上的一些东西是相互冲突的。在我找出问题所在之前，我只是将firebase(以下为：https://stackoverflow.com/a/57262942/14608654)降级为10.2.2版本，错误就消失了。|offset|length|3930830|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/57262942/14608654^0|0|0|2V|19|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

I was having the same problem and what worked for me, was as simple as changing the function's name in the file (and of course where it was called) and redeploying it, which automatically deleted the first one.
EDIT #1: I've just had the same problem again and this time, I didn't rename the function. I only deleted the function manually inside firebase and then I redeployed it. It also works.
EDIT #2: Once again I had the same problem. However, this time I couldn't fix it with the alternatives above. I had upgraded my firebase-tools and something on this new version (10.3.1) was conflicting. Until I figure out what is the problem, I just downgraded firebase-tools (following this: <a href="https://stackoverflow.com/a/57262942/14608654">https://stackoverflow.com/a/57262942/14608654</a>) to version 10.2.2 and the error vanished.

Recently I added a couple of new callable firebase cloud functions to my mobile app. The thins is, once I deployed and tested my functions I was not able to invoke them failing with an UNAUTHENTICATED error. I re-deployed all my functions and still, the old ones can be invoked while the new one failed with UNAUTHENTICATED. I did some research and people were talking about the version of the Node. I upgraded the Node version but it did not work out. I upgraded the firebase-functions version and the firebase-admin version. No luck.

I tried to browse to the URL of one of the older callable cloud functions that I have deployed before and it was ok. Then I tried to browse to a newly deployed https callable firebase cloud function. I saw this message in my browser:

Your client does not have permission to get URL /function_name from this server.

Any ideas what is going on here?

Thanks

最近，我在我的移动应用程序中添加了几个新的可调用的防火墙云功能。稀释法是，一旦我部署并测试了我的函数，我就无法用UNAUTHENTICATED错误来调用它们。我重新部署了我的所有函数，仍然可以调用旧的函数，而新的函数在未经身份验证的情况下失败。我做了一些研究，人们都在谈论Node的版本。我升级了Node版本，但没有成功...
