"Dropbox is not a constructor" Nonreasonable Error
There is a script which uses Dropbox-sdk.min.js.
The script was fully working yesterday, but today the "Dropbox is not a constructor" error is thrown, although there is the Dropbox object, as planned. Everything MUST work, but it doesn't.
SDK is linked in HTML as
<script type="text/javascript" src="https://unpkg.com/dropbox/dist/Dropbox-sdk.min.js"></script>
This line throws the error
var dbx = new Dropbox({accessToken: '***************'});
Someone, please, help me. I have tried everything therefore I am completely desperate.
UPDATE: The solution is found.
I have inspected the Dropbox object and decided to try something. And I was right.
Everything works perfect if we use
var dbx = new Dropbox.Dropbox({accessToken: '***'});instead.
I still do not know what in the world happened to the SDK that I was forced to use this workaround.
Thank you. The issue is solved.

Thanks for the report. We're looking into it. I'll follow up here once I have more information on this for you. Thank you. I count on you, because our company and I need this thing work properly as soon as possible.

The API v2 JavaScript SDK just received a major revision that includes breaking changes, with a corresponding major version bump. You can find the release notes here:
https://github.com/dropbox/dropbox-sdk-js/releases/tag/v3.0.0
This includes a change to how the `Dropbox` object is constructed. In short, as of v3.0.0, you should now use `Dropbox.Dropbox` instead.
In order to avoid major version changes from breaking your app, you can instead import specific versions of the library.
Exactly how you do so depends on where you're loading the library from.
For instance, unpkg has information on specifying particular versions here: https://unpkg.com/
