BeginCopyAsync is throwing wrong exception when source blob is not found.

[johnemmanuelm]

Which service(blob, file, queue, table) does this issue concern?

Blob (BlobCopier)

Which version of the Azurite was used?

3.31.0

Where do you get Azurite? (npm, DockerHub, NuGet, Visual Studio Code Extension)

npm

What's the Node.js version?

v20.10.0

What problem was encountered?

The exception thrown when a source blob was not found is "InternalServerError" (500) instead of a "notfound".

Steps to reproduce the issue?

If possible, please provide the debug log using the -d parameter, replacing <pathtodebuglog> with an appropriate path for your OS, or review the instructions for docker containers:

-d "<pathtodebuglog>"

Please be sure to remove any PII or sensitive information before sharing!
The debug log will log raw request headers and bodies, so that we can replay these against Azurite using REST and create tests to validate resolution.

Have you found a mitigation/solution?

No

It look related with your code change on copy source permission check.
Would you please help to look?

Hi @johnemmanuelm ,

Could share the code you used to reproduce the issue?

I tried with following code, and Azurite return 404s error as expected:

const sourceBlobClient = containerClient.getBlockBlobClient(sourceBlob);
    const destBlobClient = containerClient.getBlockBlobClient(destBlob);

    const tmr = new Date();
    tmr.setDate(tmr.getDate() + 1);

    const url = await sourceBlobClient.generateSasUrl({
      permissions: BlobSASPermissions.parse('rwd'),
      expiresOn: tmr
    });

    try {
      await destBlobClient.beginCopyFromURL(
        url
      );
    }
    catch (err) {
      err;
    }
