reading the response from {url} failed: {e}

Error message

reading the response from {url} failed: {e}

What it means

The multipart POST reached the server but reading the response body stream failed (connection dropped mid-response, decode error). This TransportError means the request's outcome is unknown — the server may or may not have processed the multipart upload.

Solutions

1. Retry the request, but check for side effects first since the operation may have already been applied
2. Investigate unstable connections, proxies, or load balancer idle timeouts between the CLI and the server
