#3942 [BUG] `pyflyte run --remote` fails to upload files to Azure Blob Storage (HTTP 400) Issue created by devictr Describe the bug When trying to run a basic workflow, I get this error:

$ pyflyte run --project flytesnacks --domain development --remote basics/hello_world.py my_wf
Failed with Exception Code: USER:ValueError
Value error!  Received: 400. Request to send data <azure blob storage URI> failed.

Doing some debugging revealed that the response from Azure Blob Storage is:

<?xml version="1.0" encoding="utf-8"?>
<Error>
    <Code>MissingRequiredHeader</Code>
    <Message>
        An HTTP header that's mandatory for this request is not specified.
        RequestId:ebd5dfbc-f01e-001d-5074-cb4f26000000

    </Message>
    <HeaderName>x-ms-blob-type</HeaderName>
</Error>

Expected behavior

pyflyte --verbose run --project flytesnacks --domain development --remote basics/hello_world.py my_wf

Should not fail and should start running a workflow. Additional context to reproduce No response Screenshots No response Are you sure this issue hasn't been raised already? ☑︎ Yes Have you read the Code of Conduct? ☑︎ Yes flyteorg/flyte
