409 reset error for list_folder/continue api from business endpoint

[saritafurtado]

I'm trying to retrieve folder items of team member by following this link https://www.dropboxforum.com/t5/API-Support-Feedback/How-to-get-all-the-files-and-folders-of-a-busin....

I am able to get result from list_folder api but when I pass cursor to list_folder/continue api I get below error.

{
    "error_summary": "reset/..",
    "error": {
        ".tag": "reset"
    }
}

Going through forum replies what I understood from this error is that the cursor is invalid or it has expired.

Please help.

Can you share the code/output for these calls so we can take a look? Thanks in advance!

I was trying this in dropbox api explorer and postman

I see you're specifying a particular 'Dropbox-API-Path-Root' header on the /2/files/list_folder/continue call. Did you also specify that for the /2/files/list_folder call?

If not, you will get this 'reset' error. You should make sure you keep the 'Dropbox-API-Path-Root' usage consistent for any particular cursor. That is, if you call /2/files/list_folder with a particular 'Dropbox-API-Path-Root' you should use that same 'Dropbox-API-Path-Root' for the next call to /2/files/list_folder/continue. (Or, if you didn't use it, omit it again.)

Yes it is working now if I put 'Dropbox-API-Path-Root'  in /list_folder api.

But while doing this I noticed two things.

1) the results fetched with the limit count is not same as limit.

Eg. /list_folder api with 'Dropbox-API-Select-User' and limit 5 gives me 5 entries and has_more true

But /list_folder api with 'Dropbox-API-Select-User', 'Dropbox-API-Path-Root' and limit 5 gives me 3 entries and has_more true.

If i use the cursor in the /list_folder/continue I get more entries. If there are more than 5 entries it should give 5 entries in first result right?

2) /list_folder  api works without 'Dropbox-API-Path-Root'?

I was using 'Dropbox-API-Path-Root' to test whether the namespace ID passed in as the root is the correct root namespace for the user. And this namespace id can change if the user joins/leaves/changes teams.

So my question is can we use /list_folder api only with 'Dropbox-API-Path-Root'? Because to retrieve members folder items you need member_id.

1) The list_folder 'limit' parameter is not a hard limit, per the documentation. It can technically return slightly more (or even less) than the limit. You should always check 'has_more' and call back to list_folder/continue if it's true.

2) You can use the 'Dropbox-API-Path-Root' header for each list_folder call, but is not required. If it is not supplied, the API will default to the "home" behavior. You can find more information in the Namespace Guide.
