Cannot use Graph API to convert minor vertion file to different file type in SharePoint

Question

The file type conversion request call cannot get the minor version file in SharePoint (e.g. 0.1, 0.2, 1.1), but it can only get major version (1.0, 2.0)

The library setting already set anyone with read right can see the minor version files. any configuration is missing to enable it?

await GraphClient.Sites[siteId].Lists[libID].Drive.Items[ItemID].Content  
                            .Request(new List<QueryOption>  
                            {  
                            new QueryOption("format", "pdf")  
                            })  
                            .GetAsync();

Hi @Johnson Yau ,

Do you want to use the Graph API to get the minor versions of the file in SharePoint? if yes, please try to use the following Graph API to get the minor versions:

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/versions?$select=id,lastModifiedDateTime  

Here is my test result:

You can use the following Graph API to get the specified minor version of the file:

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/versions('0.4')  

Hope it can help you. Thanks for your understanding.

Answer 2

Hi @Johnson Yau ,

As per my test, convert drive file works fine with GET /drive/items/{item-id}/content?format={format}, see below my test results and in this test my library has minor and major versions enabled, and I tried to convert the file with 0.4 minor version.

For better understanding can you share the library versioning settings screenshot and any error message in Graph response.

Hope this helps.
