Re: Uncaught TypeError: Dropbox.Dropbox is not a constructor

Hi! This error reappeared again!

  • skezh1 Thanks for the report. The thread you originally posted in was old, so I've moved this to a new thread.

     

    There hasn't been a new release of the Dropbox JavaScript SDK recently, and I'm not seeing this issue in my own testing now.

     

    I'll be happy to help with any issues you're having with the Dropbox API/SDK, but I'll need some more information. Please reply with:

    • the name and version number of the platform and SDK/library you are using
    • the steps to reproduce the issue, including relevant code snippet(s), but don't include any access or refresh token(s)
    • the full text of any error or unexpected output

      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!

    Unfortunately I am receiving a similar error when using the Embedder, which has worked successfully in my app for years: 

     

    Uncaught TypeError: Dropbox.embed is not a function
    at dropins.js:1:36970
    at E.init (dropins.js:1:37032)
    at HTMLDocument.w (dropins.js:1:24186)

     

    I tried moving the dropins.js before the sdk inclusion as suggested by another post in the community, but this seems not to resolve it:

     

    <script type="text/javascript" src="https://www.dropbox.com/static/api/2/dropins.js" id="dropboxjs" data-app-key="MY_KEY"></script>

    <script src="https://unpkg.com/dropbox/dist/Dropbox-sdk.min.js"></script>
