Unable to add blob tags via iot blob upload

Hi.

As the title states, I am unable to add blob tags to blobs uploaded via the iot hub.

Following your guide : https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/iot-hub/iot-hub-python-python-file-upload.md it should be as simple as

# Upload the specified file
with BlobClient.from_blob_url(sas_url) as blob_client:
    with open(file_name, "rb") as f:
        result = blob_client.upload_blob(f, overwrite=True)
        blob_client.set_blob_tags({"test":"tag"})
        return (True, result)

However this yields a <Error><Code>AuthorizationPermissionMismatch</Code><Message>This request is not authorized to perform this operation using this permission.

On the other hand i am able to add metadata

# Upload the specified file
with BlobClient.from_blob_url(sas_url) as blob_client:
    with open(file_name, "rb") as f:
        result = blob_client.upload_blob(f, overwrite=True)
        blob_client.set_blob_metadata({"test":"tag"})
        return (True, result)

Is there any workaround around this? Adding the correct permissions to the iothub for instance. I know this does not fit in the python sdk per se, but if you can point me to the correct repository to post this then ill gladly reupload.

Hi @lev-i .

Im glad they are working on a fix.

For anyone else browsing this issue : Our fix is to have an azure function with a blob trigger, that takes the metadata and adds that as tags. It works, it is not very complex, but of course it would be a better solution if it was not there at all.

@petoor As Tim pointed out, this was an issue on the C# SDK. I don’t believe it was solved on there, and likely won’t be solved here either assuming the same constraints are present. I’ll reach out to that team and see if it’s been updated at all, and I’ll let you know what I find out.
