Dropbox api v2 null - Do you want to allow this page to open “(null)”?

What would be causing my app to show "null" when running a Mac OS app called "ezReceiptMac" ? It is pointing to an existing Dropbox APP ID called "ezReceipt". My Mac OS app is sandboxed and has "Inco...

Thanks! The expected result here is that the dialog would show the app name, and clicking "Allow" would send the user back to the app.

Can you share your plist file? That controls how your app is registered for this. In particular, for the null app name issue, I think CFBundleIdentifier may be relevant.

Yes please see the plist file below. The app id has been removed.

    Thanks! I was able to reproduce the issue by removing the value for CFBundleIdentifier. Yours is $(PRODUCT_BUNDLE_IDENTIFIER), so make sure that "Product Bundle Identifier" is set in your target's Build Settings. That's listed in the Packaging section.

      The "Product Bundle Identifier" has been set in the target's Build Settings the whole time.

      Still seeing the "null" issue.

        Thanks for checking that. It does look like that should be getting filled out then, so I'm not sure exactly what's causing it on your system. In testing this, I was actually able to get mine stuck on null as well though. I was able to fix it by:

         

        • running "Clean Build Folder" (in the Xcode "Product" menu, while holding down option)
        • running "Clean" (in the Xcode "Product" menu)
        • deleting the contents of ~/Library/Developer/Xcode/DerivedData

        I believe the last step is the one that fixed it for me, but I'm listing them all just in case. It looks like I had multiple old builds in the DerivedData folder, at least one of didn't have a CFBundleIdentifier, which may been what macOS was loading for the name.

         

        Can you try those?

         

        Alternatively, if the issue is with your project settings somehow, you may want to try just manually filling in the CFBundleIdentifier in your plist directly, i.e., with the $() variable.
