    Thanks, do you want me to open an issue in Github for Version 5.0.0 ?

    Because I checked with Version 4.0.30 and there it still works perfectly.

    Regards Martin

      Thanks, but there's no need to open this as an issue on GitHub as well. We're aware of the issue and are working on resolving it. I'll follow up here once I have an update on this.

    We experienced the same error yesterday, and the time of the failure coincides exactly with the release of to the v5.0.0 tag.  This broke the integration for our entire customer base. We've now rolled back to v4.3.0 as an interim measure.

     

    If breaking changes are introduced, where does Dropbox announce upcoming breaking changes? I can find nothing in the developer blog.

      The Problem has been fixed yesterday evening (Vienna Time). It works for me again.

      You can use the newest version again. It is now 5.1.0

      Regards

      sareuon That's correct, this was caused by an unintentional bug in v5.0.0. It was subsequently fixed in v5.1.0. You can find release notes for the different releases in the release history here.

       

      For reference, we generally follow semver for the SDKs, so any intentionally breaking changes would be accompanied by a major version increase (such as from 4.x to 5.x like we had here, though this particular issue was unintentional). For this reason, to avoid breaking changes in your production app, you can import a specific version of the library instead of just always importing the latest version.
