blazor documenteditor SaveAsBlob throwing nullreference exception

[Ywein Van Den Brande]

I am using this example (https://blazor.syncfusion.com/documentation/document-editor/saving-document/#save-document-to-server) to send a document to the backend.

        SfDocumentEditor editor = container.DocumentEditor;

        string base64Data = await editor.SaveAsBlob(FormatType.Docx);

        byte[] data = Convert.FromBase64String(base64Data);

 the SaveAsBlob line is throwing a nullreference exception. I have verified that the editor is not null. I am using the latest version 19.1.0.54

Hi Ywein, 

Syncfusion Greetings! 

We couldn’t reproduce the reported issue. We suspect that the reported problems are might be due to the contents in the input word document which used at your end. We need to investigate with the contents in your input Word document to reproduce the exact problem at our end. So, could you please provide us the input Word document which used at your end. Thereby, we will analyze further and provide you the appropriate solution at the earliest. 

  

Note: If you have any confidential data in your Word document, please replace with some dummy data and provide us the same. We just need your document to recreate the problem you face.

I don't think it is because of the input document. I am getting the exception even if I use the exact 'Save document to server' example in the link, so without any input document.

I send you a reproduceable example in attachment.

Here is the error:

Hello, I'm encountering the same Task Cancelled exception when using FormatType.Html. It works correctly with FormatType.Docx. Using version 20.2.0.40.

The link you provided in your reply does not work for me, so I don't know what it is referring to.

Both SaveAsBlob and SaveAsBlobAsync give the same result.  The task appears to "run" for a while, then eventually throws the exception.

Hi Charles,

SaveasBlobAsync API will not accept the parameter as FormatType.Html.

If your requirement convert the document to html format, please get the string using "FormatType.Docx". Then convert the document to HTml with the help of Synfusion DocIO.
