Hi @박 준혁 ,
Based on my test with driveitem-get-content-format, it works fine see my test result.
GET /drive/items/{item-id}/content?format={format}
Also, the observations on the logs indicate, the error status code [302] generalException and the Graph API returned the response from the word online workload must have timed-out to convert the file.
- Try with increasing the request time for the request
Hope this helps.
