[BUG] User Delegation Key signed SAS not working with SharedAccessBlobHeaders

[smiroslav]

It seems that unused headers have to be set to empty explicitly. Otherwise, because of the code below, their values become null in the string to be signed
https://github.com/Azure/azure-storage-java/blob/v8.6.6/microsoft-azure-storage/src/com/microsoft/azure/storage/core/SharedAccessSignatureHelper.java#L409-L420

With this change code works

        SharedAccessBlobHeaders headers = new SharedAccessBlobHeaders();
        headers.setCacheControl(String.format("private, max-age=%d, immutable", 900));
        headers.setContentDisposition("");
        headers.setContentEncoding("");
        headers.setContentLanguage("");
        headers.setContentType("");

Hi @t-rana someone from the Storage team will follow up with you shortly, but please note that 8.6.6 is a very old SDK from 2019 that has been superseded by much newer versions (if you follow the This artifact was moved to links on maven central they'll lead you to the latest 12.25.x version here https://mvnrepository.com/artifact/com.azure/azure-storage-blob). It's highly recommended that you upgrade from version 8 to version 12.

Hi @t-rana
The SDK version you are using is very old and it is advised that you upgrade to version 12 since there are many changes we've introduced since that may help in avoiding the issue you're seeing.
Suggestion provided by @smiroslav seems to be correct. Are you unblocked now or still experiencing issues?
