Failure to upload file > 100MB using Microsoft Graph SharePoint Connected System

A Score Level 1

Hi, we have a functionality to upload a file and save it in a folder in SharePoint. The connected system we are using is through the HTTP integrated Microsoft Graph Connected System. It works fine for a file size up to 100MB but post that we are facing Integration Error as [title=There was a problem with the request, message=Failed to connect to https://graph.microsoft.com/v1.0/drives/b!m6Ln0pXy60eQAb14pUvBiE4NVb13D6JDnJVPxlNZJEQw55MIsIdnQa8ktIM9MLWk/items/01HO3UJFSOHDXPAJQEDRA2S5JCHFKWTKGT:/MS_dummy_file_250MB20242245_024518.bin:/content, detail=HTTP/1.1 499 ]. Please can one suggest how to resolve this issue so that files with larger size can be uploaded using same connected system.

    We have the same problems, we need to upload large files and to do so we have to cut the file into pieces to send it to the msgraph API. I have not found a way to divide the file in appian, so we have decided to do it with a middleware made in java that acts as an intermediary between appian and sharepoint, and is the one who divides the file to send it to msgraph. API. If you can think of a way to do it in appian, please comment.
