Hello developers,
I am currently working on integrating Smartsheet API into my application and have encountered an issue related to image uploads using the Smartsheet SDK.
The specific error message I'm encountering is: "Only images can be uploaded. Please use a file of type jpg, gif, or png." I have already ensured that the content type is set to "image/jpeg," and the file being uploaded is indeed a valid JPEG image.
Here is the code:
public void AddImageToCell(long rowId, string columnName, string altText, string imageURL)
{
string tempFilePath = DownloadImage(imageURL);
try
{
long columnId = (long)GetColumnIdByName(columnName);
string contentType = "image/jpg";
RowColumnResources rowColumnResources = _smartsheetClient.SheetResources.RowResources.CellResources;
rowColumnResources.AddImageToCell(_sheetID, rowId, columnId, tempFilePath, contentType, true, altText);
}
catch(Exception ex)
{
throw ex;
}
finally
{
if (File.Exists(tempFilePath))
{
File.Delete(tempFilePath);
}
}
}
---------------------------------------------------------------------------------------------
private string DownloadImage(string imageUrl)
{
string tempFileName = "temp_image.jpg";
using (var client = new WebClient())
{
client.DownloadFile(imageUrl, tempFileName);
}
return tempFileName;
}
It was working in the older versions but in the latest one it is not.
