"Failed to construct 'Blob': The provided value cannot be converted to a sequence" when downloading file
The first parameter should be sequence.
Thus, this will not work:
let blob = new Blob(data, { type: "application/pdf"});But this will:
let blob = new Blob([data], { type: "application/pdf"});
This is what I ended up with:
public HttpResponseMessage GetPdf(){ var pdf = generatePdfByteArray(); var result = Request.CreateResponse(HttpStatusCode.OK); var dataStream = new MemoryStream(pdf); result.Content = new StreamContent(dataStream); result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "file.pdf" }; result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf"); return result;}
