PathRootErrorException received on listFolder

Highlighted

PathRootErrorException received on listFolder

Explorer | Level 4

Hi,

 

I'm working with Dropbox Java SDK for ARES Kudo (kudo.graebert.com) and we're facing weird exceptions sometimes from some of our users. The exception is com.dropbox.core.PathRootErrorException in response to listFolder("") call (list "root" content)

 

I've tried to find out the reason, but wasn't able to. I don't get any messages except the exception. It's rarely reproducible - around 2-3 times in 2 weeks.

 

Any ideas what it can be?

Thanks for the following up with this additional information. An 'invalid_root' error like this means:

The root namespace id in Dropbox-API-Path-Root header is not valid. The value of this error is user's latest root info.

That is, you're sending the wrong value up in withPathRoot. Note that a user's root namespace ID can change over time, e.g., due to team changes. You can find more information on this in the Team Files Guide and Root Header Modes Guide.

 

You should have your app catch these automatically change the root used for the user accordingly. You can get the new root information directly from this error, or by checking the user's root information again like you would have originally.

You should be able to get a PathRootError with more error information via PathRootErrorException.getPathRootError. Can you try implementing that in your error handling to get some more information on the issue?

Hi,

 

Thank you for fast response! I've added logging for information from getPathRootError. 


As I don't know stable way to reproduce - I'll check logs next week to see if there are any additional info and will post it here.

Hi,

 

I've checked - there are 4 occurences from the last 2 weeks. All from the same account.

 

Here's the output from getPathRootError:

{".tag":"invalid_root","invalid_root":{".tag":"team","root_namespace_id":"5720228768","home_namespace_id":"2871343088","home_path":"/Tom Holt"}}

Any ideas? Does it have something to do with team folders? 

@Greg-DB Can you help?
