I am working on an azure function app that copies files from one sharepoint site to another on the same tenant. We copy the files using Microsoft.Sharepoint.Client.Site.CreateCopyJobs CSOM api and then after the copy is finished we have to update sharepoint fields on the file for business reasons.
For the field updates we make a PATCH request using microsoft graph but for large files (seems to be > 500MB) the patch request times out with a 504 error after 30 seconds.
We had switched from using CSOM to graph API for similar errors. How can I ensure that fields on large files are getting updated? Is there a different API I should be calling for updating files of this size ?
