Graph API- post request

Hi,

I am trying to write to an excel sheet using the graph api.
The call is something like this:

var ts = new GraphQueryable(graph, /sites/${siteWebIds}/drives/{driveId}/items/{itemId}/workbook/worksheets/
{excelSheetName}/tables/{tableName}/rows/add);`

ts.setEndpoint("beta");

ts.get().then(function(results){
console.log(results); // the get request is working
});

ts.post(workbookTableRow); // the post request is failing

Looks like the plumsail graph api library does not include all the functions/features of the original graph api. Or is there something that I am not doing right?

Is there another way of doing that other than the power automate? I am trying to write to the excel document stored in a document library on form load/render.

Dear @Mai,
Not everything is included with Plumsail Forms Graph API that's true, but Graph client is extensible with GraphQuerable - all missing methods can be replicated with it.

I would recommend to check the Network tab in the browser's DevTools and make sure that the request you've formed is right and check what it returns.
