I’m trying to upload an image to a specific SharePoint list using the Microsoft Graph REST API v1.0, but I’m having a hard time understanding how to do it correctly. I’ve been looking for documentation and examples, but haven’t found a clear solution yet.

How to upload an image to a sharepoint “LIST” using Graph?
In my case I already managed to upload a file to a folder as a document by converting the
image to an array of bytes.

It was really easy to upload images to a document library in SharePoint.
BUT The idea is to upload the image to a LIST and it is required that it be an image type, I don’t know what you expect the API to send there.

A SharePoint list item is a row of data in a SharePoint list, which is a collection of information organized into rows and columns.

I have tried several methods in the documentation without obtaining any results.

graphClient.Sites[siteId].Lists[listId].Items[itemId].Fields.Request().UpdateAsync(fieldsToUpdate);
graphClient.Sites[siteId].Lists[listId].Items[itemId].Fields.Request().CreateAsync(fieldsToUpdate);
graphClient.Sites[siteId].Lists[listId].Items.Request().AddAsync(ListItem);

In the documentation there are no examples of mounting an image:
https://learn.microsoft.com/en-us/graph/api/listitem-create?view=graph-rest-1.0&tabs=csharp

They create a JSON but send only plain text.

I have also sent the address of the image but I get an error.

THIS IS MY CODE:
My method that uploads to a folder does it fine.

but I haven’t had any luck with this one on the list:
