invalid_revision error while restoring file version through api

The /2/files/restore endpoint is the right way to restore a previous version of a file. An 'invalid_revision' error like that should indicate that the value you supplied in the "rev" parameter isn't usable though, e.g., it's not an actual revision value, or it refers to a version that cannot be restored (e.g., because it doesn't exist anymore).

If something's not working as expected/documented, I'll be happy to look into it, but I'd need some more information. In that case, reply with:

• the name and version number of the SDK/library you are using, if any
• 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,
Thanks for the response.

Actually I am trying to restore a deleted file through this API.
But its showing this "invalid_revision" error.
Also the file I am trying to restore is deleted within 30 days. (2-3 days before)

What can be the reason, anything to help here?

I am using Dropbox Java SDK v4.0.1
Error message I am getting - Exception in 2/files/restore: "invalid_revision"

Hi AmanSingh,

How and where did you get the revision from, that gets refused here as an invalid? 🤔 Can you describe exact steps or, as Greg-DB has mentioned above, share some code snippet reproducing the issue?

AmanSingh Yes, as Здравко mentioned, please share the relevant code. It would be useful if you show both where/how you're get the revision value, as well as where/how you're using it. It may also be helpful for troubleshooting purposes to print out the value itself.

AmanSingh The listFolder/listFolderContinue methods are the right way to list the contents of a folder, the listRevisions method is the right way to list the versions of a file, and the restore method is the right way to restore a deleted file. I just gave these a try myself and they are working properly for me. If it's not working for you, please share the rest of the relevant code and output so we can take a look at what's not working for you specifically. Thanks!

Hi,

Thanks for the information.

So, that's my sample code - 

String path = "/testaman6.dwg";
List<FileMetadata> revisions = new AWSXRayDbxClientV2(api, xRay).files().listRevisions(path).getEntries();
String rev = revisions.get(0).getRev();
new AWSXRayDbxClientV2(api, xRay).files().restore(path, rev);

Inputs for restore function - 
path - /testaman6.dwg

rev - 015d183052af6b300000002296c5930

Error I am getting - Exception in 2/files/restore: "invalid_revision"

AmanSingh Thanks! That code itself looks fine, so it sounds like there's something specific to your account/files relevant here. Could you please open an API ticket and share the entire output you get from 'new AWSXRayDbxClientV2(api, xRay).files().listRevisions(path)' itself? That should help us investigate internally. Thanks in advance and apologies for the bother.

Thanks for the information.

I have raised a ticket for this - https://www.dropbox.com/support/ticket/15701428

Hope for a quick response.

Thanks
