Error message

Some files failed to sign:\n

What it means

After signing, outputs are verified (hashes etc.); files that fail verification are collected into a failures list and reported together in one aggregate error at the end of the signing run.

Solutions

1. Read the per-file bullet lines in the error to see exactly which files failed and why
2. Fix the root cause (auth, disk, service availability) and re-run the signing task
3. If transient, retry the signing step, then verify sha256 hashes of the outputs manually

try { await signAll(files); } catch (e) { if (/Some files failed to sign/.test(e.message)) { log the failure list; await delay(backoffMs); return signAll(files); // signing is idempotent per file } throw e; }

When it happens

Trigger: Signing-service errors, partially written outputs, post-sign hash mismatches, or unreadable signed files add entries to failures and trigger this error.

Common situations: Transient signing-service/network failures; code-signing auth problems; antivirus or post-processing modifying files after signing on Windows.
