Hi, I’m getting this error: Value cannot be null. (Parameter ‘image’) trying to convert a Word to HTML using the following function(error in document.Save):
[HttpPost("convert-word-to-html")]
public async Task<IActionResult> ConvertWordToHTML(IFormFile file)
{
if (file == null || file.Length == 0)
{
return BadRequest("Please upload a valid Word file.");
}
try
{
using (var stream = new MemoryStream())
{
await file.CopyToAsync(stream);
stream.Position = 0;
ComponentInfo.SetLicense(ImportUtils.gemBoxSerialKey);
ComponentInfo.FreeLimitReached += (sender, e) => e.FreeLimitReachedAction = FreeLimitReachedAction.ContinueAsTrial;
var document = DocumentModel.Load(stream);
CapturerByText capturer = new CapturerByText(document, null);
// Convert the document to HTML string
var saveOptions = new HtmlSaveOptions()
{
HtmlType = HtmlType.HtmlInline,
EmbedImages = true,
UseSemanticElements = false
};
string htmlName = "Exported.html";
// Save DocumentModel object to HTML (or MHTML) file.
document.Save(htmlName, saveOptions);
// Returns the content of Exported.html and then remove the file
var htmlContent = System.IO.File.ReadAllText(htmlName);
System.IO.File.Delete(htmlName);
return Ok(new { html = htmlContent, hasHeadingStyles = capturer.hasHeadingStyles(), stylesFromDoc = capturer.getStylesFromDoc() });
}
}
catch (Exception ex)
{
return BadRequest(ex.Message);
}
}
Could you guide me on what I should check in the Word file?
