When using Sharepoint Migration Tool on a language other than English to copy files to the default "Shared Documents" (or "Documents" as you are to use), it gives Invalid SharePoint Online list 'Documents' (ErrorCode: 0x0201000D). Whats the correct Document Library name to use?
It seems a Language issue. Make sure that the language settings of the user used in SharePoint is set to the same language as the original site creation default language.
Or use the same language that SharePoint Migration Tool used for library name.
