Azure Storage Javascript library getcontainerclient error

Question

I am using @azure/storage-blob library in angular. I get the BlobServiceClient and then call the getContainerClient method and recieve the following error:

"Uncaught (in promise): TypeError: Failed to construct 'URL': Invalid URL TypeError: Failed to construct 'URL': Invalid URL"

var client = new BlobServiceClient(`https://mystorage.blob.core.windows.net${sas}`);
let containers = client.listContainers();
const containerClient = client.getContainerClient('containerName');

I've search but an unable see if I am doing something wrong..

To perform a GetContainerClient operation, you would need a service SAS. This can be created from the Azure storage account portal as shown below:

Sample code to call the GetContainerClient using SAS token is here:

const { BlobServiceClient } = require("@azure/storage-blob");

const account = "<account name>";
const sas = "<service Shared Access Signature Token>";
const containerName = "<container name>";
const blobName = "<blob name>";

const blobServiceClient = new BlobServiceClient(`https://${account}.blob.core.windows.net${sas}`);

async function main() {
  const containerClient = blobServiceClient.getContainerClient(containerName);
  const blobClient = containerClient.getBlobClient(blobName);
...
...

}

If you want to create Service SAS token for a Azure Blob Storage container using javascript, you can refer this sample code. Hope this helps.
