seems to work fine Looking at the source code where the exception is coming from (IOConnection.java:302, from the inner NullPointerException), there's this block of code: if (connection instanceof HttpsURLConnection) {
((HttpsURLConnection) connection)
.setSSLSocketFactory(sslContext.getSocketFactory());

Null pointer exception and Table "SYNONYMS" not found error in H2 console in corda

Itext7 convert html to pdf (asp.net core 2.1) get error "Cannot access a closed stream"
Date : March 29 2020, 07:55 AM
hop of those help? HtmlConverter.ConvertToPdf closes the stream that was passed to it after the conversion process is over. However, because you are using a MemoryStream, you can still access its content even after it was closed. If you want to use the contents as a stream again, you can create a new one and use it afterwards: MemoryStream pdfStream = new MemoryStream(stream.ToArray());
await blockBlob.UploadFromStreamAsync(pdfStream);
pdfStream.Dispose();
