Smoke test is failing for storage-blob-changefeed with below error. Currently smoke test is disabled for this package. We should reenable this test once issue in this sample testing is resolved.

How is the process env set in the smoke-test environment? Does the account has the change feed feature enabled?
Which config is smoke-test using to create the accounts for testing?
Change feed samples use the credentials in the same way as other storage packages. I wonder why it is failing with authentication error.
There is some "The container ($blobchangefeed) does not exist" errors in the log. If that's the real cause, the it's probably due to the change feed feature isn't turned on.

We haven't figured out how to enable live tests for change feed as the enabling may take some time to take effect. So skipping the change feed samples is the right thing to do for now till we figure it out.

import * as dotenv from "dotenv";
dotenv.config();

export async function main() {
  // Enter your storage account name and shared key
  const account = process.env.ACCOUNT_NAME || "";
  const accountKey = process.env.ACCOUNT_KEY || "";
...
}

The test account is deployed with this ARM template:
