ElevenLabs local file operation failed: {exc}

Error message

ElevenLabs local file operation failed: {exc}

What it means

Catch-all in generate_bgm for OSError raised outside the HTTP call — i.e. during _create_video_proxy (FFmpeg re-encode to a <=200MB proxy) or file moves. ElevenLabsMusicError is re-raised untouched; only raw OS-level failures get wrapped with the underlying exc text.

Solutions

1. Check the embedded exc text: 'No such file or directory' with a subprocess usually means the ffmpeg binary is missing — install it or fix PATH
2. Free space or point TMPDIR at a volume large enough for the proxy (up to 200MB) plus audio output
3. Ensure output_path and temp dirs are on writable mounts
4. Keep temp and output on the same filesystem so os.replace stays atomic

Example fix

# before
proxy_path = _create_video_proxy(video_path)  # ENOSPC mid-encode, opaque

# after
import shutil
if shutil.disk_usage(tempfile.gettempdir()).free < 500 * 1024 * 1024:
    raise OSError(f"insufficient temp space for proxy: {tempfile.gettempdir()}")
proxy_path = _create_video_proxy(video_path)

import shutil

assert shutil.which("ffmpeg"), "ffmpeg binary required for proxy creation"
assert os.access(os.path.dirname(output_path) or ".", os.W_OK)

try:
    elm.generate_bgm(...)
except elm.ElevenLabsMusicError as e:
    if "local file operation" in str(e):
        check_disk_and_paths()  # surface ENOSPC/permission detail to ops
    raise

When it happens

Trigger: FFmpeg subprocess spawn fails (binary not found), the proxy write hits ENOSPC (disk full), permission errors on temp/output directories, or os.replace across filesystems raising OSError.

Common situations: ffmpeg/ffprobe not installed or not on PATH in docker images, /tmp too small for a 200MB proxy of a long video, read-only output volume, or temp dir and output dir on different mounts.
