Describe the bug
When we try to interact with a Data Lake Gen2 Storage Account where HNS is enabled we receive the error.
The same function is working fine with a Storage account where HNS is disabled.
When we revert to version 12.0.0 the same function (e.g.: DataLakeFileSysteClient.exists()) is working.
To Reproduce
getClient() {
if (!this.client) {
this.client = new DataLakeServiceClient(
https://${this.accountName}.dfs.core.windows.net,
this.credentials
);
}
return this.client;
}
let fileSystem = this.getClient().getFileSystemClient(this.fileSystemName);
let exists = await fileSystem.exists();
Could you share me the request id of the failing request?
This is bizarre because 2020-04-08 should have already been rolled out in the production environment.
@ljian3377 I'm encountering the same kind of InvalidHeaderValue issue (although with a slightly different use case).
The following code (leveraging @azure/storage-blob 12.4.0) works ok against a DEV storage account, but fails against a TEST storage account.
_Note:_ both DEV and TEST storage accounts are standard_LRS storage v2 and have been created using the exact same ARM template. However, they live under different subscriptions.
try {
const { BlobClient } = await import("@azure/storage-blob");
const bc = new BlobClient(cn, "[REDACTED]", "[REDACTED]", undefined);
const buf = await bc.downloadToBuffer();
return buf.toString();
} catch (e) {
const content = JSON.stringify(e);
console.log(content);
await Fs.promises.writeFile("./err.json", content, 'utf8');
throw e;
}
The content below is the output of err.json when ran against our TEST environment

@ljian3377 The same exact code works perfectly against both our DEV and TEST storage accounts when using @azure/storage-blob v12.3.0
@nulltoken The server hit is not rolled-out with the right configuration. Already notified the service team to fix it.
@jbreunung
Could you share us the failing request's requestId or your account name so that we can locate the server and fix it for you?
@ljian3377 Awesome feedback! Thanks a lot. How could I monitor on my side the rollout? Is there an API I could call to check for a version change or a specific blade in Azure Portal?

I am afraid not. I have asked the service team to notify you here when it's fixed.
@nulltoken
It should be working now. Could you retry?
It should be working now. Could you retry?
@ljian3377 Everything is 200 OK now on my side! Thanks you so much for your tremendous help and amazing support! <3

Hi together,
i am working with @jbreunung. It seems you fixed the problem. i can no longer reproduce the issue with version 12.3.0 to create a failing request id.
Thanks a lot for the very fast reply!
