I am migrating a SharePoint Document library from SharePoint 2013 to SharePoint Online, I am getting multiple errors in the migration task folder with the following message: Message:An item with the same key has already been added. The folder contains 6500 pdf documents and any of them is moved to the sharepoint online. The complete error is the following:

There is a error for each file in the source.

    Hi @Sergio Cano ,

    Per my test, I am not able to reproduce your issue. Is this issue with the only folder/library? Try to test in other library to compare the result.

    And please remember to perform migration tasks with the official guidance:
    Overview of the SharePoint Migration Tool (SPMT)
