Re: Uncaught TypeError: Dropbox.Dropbox is not a constructor
Hi! This error reappeared again!
Hi Greg and thank you for replying so quickly!
I've built a web app that had been up for a few years and I did not make any recent updates there, but it started to fail today with the "TypeError: Dropbox.Dropbox is not a constructor" error on the "new Dropbox.Dropbox({accessToken: *** })" (Credentials replaced) line.
I've tried updating the SDK version to the latest (10.34.0 now, and I'm using an older version) - this did not fix the issue. SDK version 5.1.0 that did fix this issue last time - also did not help.
Confused, I went to tutorials, and was able to successfully call dropbox from my app with the "basic" example (https://github.com/dropbox/dropbox-sdk-js/tree/main/examples/javascript/basic) , but I could not find the problem still on why this started to happen. I tried to move the line to the global namespace like in the example - this also did not help.
Eventually, I figured that replacing "new Dropbox.Dropbox" with just "new Dropbox" resolved the issue for me - all the functions were there. I've added a try-catch to try both options for now so that my app will continue working.
If I find what the issue was - I will update!
Thank you!
Found the way to reproduce and the issue!
So, the problem happens if the following library is included after Dropbox-sdk.min.js:
https://www.dropbox.com/static/api/2/dropins.js
Please see example here! https://jsfiddle.net/y9dm8oew/
Run it and open the console to see the error.
Hi skezh1,
Yes, of course, it's obvious. Both scripts share the same namespace and put there the same name - the last wins. 🙋 That's where your issue is coming from.
By the way you're not using neither Embedder, Saver, or something like... hy at all you need the second script? 🧐 Just to make your life difficult? 😁
A workaround can be seen here if by any chance you need both scripts. 😉
Good luck.
Thank you!
I'm using the Saver in my app. The above was just a minimal sniplet to reproduce the issue.
Question remaining is why now this started to happen?
Did the dropin library had changes to it that started to overwrite the Dropbox class instead of extending it, and if so - was the change intended and probably documentation should be updated, or is it a bug?
We are facing the same issue in our company, both Dropbox.Dropbox and Dropbox.embed is undefined, but Dropbox and embed are available on window
I tried the workaround, but then Dropbox.embed errors out with the following message:Error: appKey must be provided at o.e (dropins.js:1:24651) at new o (dropins.js:1:31456) at Dropbox.embed (dropins.js:1:36121)
the only thing that could have changed is the dropins.js file, as we serve our own copy of Dropbox-sdk.min.js from cdnjs.
Edit: got it to work, had to piece together the Dropbox object<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/dropbox.js/10.34.0/Dropbox-sdk.min.js"></script> <script> const dropbox = Dropbox; </script> <script id="dropboxjs" type="text/javascript" src="https://www.dropbox.com/static/api/2/dropins.js" data-app-key="..."></script> <script> Dropbox = { Dropbox, ...dropbox } </script>
