Error Header 'x-ms-apim-tokens' not found when listing files in a folder using onedrive connector

Posted on by ak1

My flow is extremly simple, I have a manual trigger which list all files in a folder using onedrive connector.

There are 7000+ files in the folder so I have turned pagination on. The settings can be seen below

If I turn the pagination off it works and lists 20 files. If I turn it on I get the error below

Does anybody know where am I going wrong?

Hi @ak1,

Could you please share a screenshot of your flow's configuration?

I have made a test on my side and don't have the issue that you mentioned. My flow's configuration as below:

Note: I have enabled the Pagination option within the "List files in folder" action.

The flow works successfully as below:

Please consider take a try to remove this action and re-add it again to check if the issue is solved. In addition, please also take a try to re-create a new connection to this connector and try the action again on your side.

The user @DanielNunes has faced same issue with you, please check the response within the following thread:

Hi Kris,

Thank you for such a detailed response.

My flow configuration is as follows, followed by the settings for listing the files

Please consider take a try to remove this action and re-add it again to check if the issue is solved.
Did not work 😞

The solution here was just to delete and try again which I've already done

If the folder has less than 20 items then it works fine. So I'm assuming the error is only there when pagination is there.

Leaving this here for anyone with a similar but distinct issue:

I had this same error in a child flow that was caused by run-only user permissions for the sharepoint connector, and when I changed that to use a different connection (from "Provided by run-only user" to "blahblah@companyname.com") it started working.
