Error message when saving to Dropbox

[Jesus Garcia]

How can I save my file?

[David Benson]

Can you share the details with us?

I'm trying to save to Dropbox and keep getting "Access Denied"

[David Benson]

Do you have any browser extensions, like an ad blocker, that would prevent the dropbox domain being reached?

[Jesus Garcia]

Not that I'm aware of

[David Benson]

Could you give us detailed reproduction steps please, see https://www.chiark.greenend.org.uk/~sgtatham/bugs.html for how to report problems in detail.

I simply created a flowchart and have reached a point where I want to save all my work. I click on the "Unsaved Changes. Click here to save" button. In the Pop up window, I name the file, choose Dropbox and Authorize. Then I get "Access Denied".  This is getting to be frustrating!

[David Benson]

Are there any errors on the browser console?

I'm having same issue. I have draw.io on my allowed apps in Dropbox, but still can't open from or save to. Keeps asking to "Authorize" draw.io. But it is. Just tried in icognito mode (no extensions on Chrome) - same results. Folder "Apps/drawio" exists.

Looks like Dropbox API updated, and drawio uses old stuff (just a guess).

Draw.io does bad requests:

POST https://api.dropboxapi.com/2/files/get_metadata 400 (Bad Request)

POST https://content.dropboxapi.com/2/files/upload 400 (Bad Request)

Error message in the response body:

Error in call to API function "files/get_metadata": The given OAuth 2 access token is malformed.

The error message suggests there is an error with the access token, which is created when you login. Have you tried signing out and back in again?

I'm having the same issue as above.  When I log into my dropbox account,  Draw.io shows as an already authorized app, 

 however 

1)   when I try to save a file from the "Save as"  menu and select Dropbox as a location, the "Authorization required" screen comes up.  

2)  I click "Authorize" . and get " Access denied"   the access denied popup has a try again button, but no matter how many times I try again,  the "Access denied screen comes up.

Now if I just go to draw.io from a browser the save to Dropbox option that used to have Dropbox as one of the options has disappeared.  The UI now only offers,  Google Drive,  OneDrive and Device.  The Dropbox option is no longer there for me.  If I hit "decide later " and make a chart and later go to "save as" . the dropbox option is still there to save to, but I get the " Access denied" response when I try to save there...

Now,  once a few months ago when I created a chart and wanted to save to dropbox,  I accidentally hit " don't authorize"  dropbox.  This might have created my problem.  BUT, since then I've tried to Authorize Dropbox 40 times and as I mentioned Draw.io shows up in my Dropbox account as an authorized app,  but I just keep getting the access denied message when I try to save there..

Does anyone have a suggestion to fix this?  I have deleted and re-added Draw.io to my authorized apps in Dropbox but that didn't solve the problem.
