wrangler secret bulk failed: duplicate secret name

wrangler secret bulk failed: duplicate secret name

TL;DR

The secrets file lists the same secret name twice and wrangler refuses the bulk upload. Dedupe the file (one entry per name), then re-run. Bulk upload is all-or-nothing on names.

wrangler secret bulk failed: duplicate secret name

Steps

1. Open the secrets file and find the duplicated name. Expected: The duplicate is visible.

2. Merge or remove the duplicate entry so each name appears once. Expected: The file is clean.

3. Re-run wrangler secret bulk. Expected: The upload succeeds.

4. Validate the file in CI (a uniqueness check) before upload. Expected: Duplicates never reach wrangler.

5. Verify the deployed secrets list matches expectations. Expected: The right values are live.

When to use

• secret bulk fails on duplicate names
• the secrets file is hand-edited
• merging secrets from multiple sources

When not to use

• a single secret put fails (different command, different issue)
• the name is intentionally overridden (bulk does not support that; do it explicitly)
• the error is about values, not names (read it)

Tool compatibility

• wrangler
• secret bulk

Variant phrasings

• "wrangler secret bulk duplicate"
• "duplicate secret name wrangler"
• "secret bulk failed duplicate name"

Why it happens

Bulk upload maps names to values, and a duplicated name is ambiguous: which value wins? Rather than guess, wrangler fails. The file usually gains duplicates when two people add the same secret or when files merge.

Edge cases

• the check is case-sensitive; near-duplicates differing by case both upload
• bulk replaces the listed secrets; it does not merge with existing ones
• keep the secrets file out of version control or encrypt it
