So i am trying to upload an image to my blob storage and I keep getting this error

<Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

I have generated a SAS key and my code looks like this

await dio!.post( uploadUrl, data: streamData, options: Options( headers: { //Headers.contentLengthHeader: fileBytes.length, //"x-ms-blob-type": "BlockBlob", "x-ms-version": "2017-11-09", 'Authorization': 'SharedAccessSignature $sasToken', 'Content-Type': 'image/jpeg', }, ), );

With my upload URL being
String uploadUrl = 'https://palynxapp.blob.core.windows.net/palynxapp/$fileName$sasToken';

What am I doing wrong please

    Hi ProDevs - Thanks for reaching out.

    This appears to be some mismatch in SAS generations and the URL again which it might be getting called.

    Can you please verify if your container name matches the storage account name? Based on the above it appears to be the same.

    If not, then I would recommend printing the request URL once, to see if the container name matches the one in the URL.

    Please let us know if you have any further queries. I’m happy to assist you further.
