WARNING: $*

Error message

WARNING: $*

What it means

Not a failure on its own: warn() at line 31 of skills/frontend-slides/scripts/export-pdf.sh is the script's non-fatal diagnostic printer — it echoes 'WARNING: <text>' in yellow to stdout. The deck-to-PDF export continues after it (set -euo pipefail aborts only on errors). In the current revision the helper has no active call sites (err() carries the real failures), so seeing this prefix means a non-fatal condition raised by a newer/patched revision of the script — the actionable content is the text after 'WARNING:'.

Solutions

1. Read the text following 'WARNING:' — that is the actual condition; the helper itself is only formatting.
2. Rely on the script's exit code, not stdout, to decide failure — warnings do not stop the export.
3. Strip ANSI codes before grepping logs: sed 's/\x1b\[[0-9;]*m//g'.

When it happens

Trigger: Any warn '<text>' call-site added to export-pdf.sh firing under degraded-but-continuing conditions (e.g. fallback resolution, optional dependency missing); piping the script's stdout into logs or CI capture where the warning surfaces.

Common situations: Scanning CI logs and matching the WARNING prefix; ANSI color codes surviving or being stripped in log aggregation, making the line harder to grep.
