Error message

pm.vault.unset() is not supported in Hoppscotch (Postman Vault feature)

What it means

Thrown by `pm.vault.unset()` (post-request.js:3987). Completes the unsupported-vault trio; deleting a vault entry has no Hoppscotch implementation, so the method always throws. Arguments are ignored.

Solutions

Remove the `pm.vault.unset(...)` call.
Manage secret lifecycle (create/delete) in the Hoppscotch UI or CI, not in-script.
If you need to clear a local value, `pw.env.unset('key')` for env-scoped variables.
Document vault operations as unsupported during collection migration.

Example fix

// before
pm.vault.unset('apiKey')
// after
pw.env.unset('apiKey')

Defensive patterns

Strategy: validation

Validate before calling

// Don't call pm.vault.unset; clear env-scoped values if needed
pw.env.unset('apiKey')

Prevention

Remove `pm.vault.unset(...)` calls.
Manage secret lifecycle in the Hoppscotch UI or CI, not in-script.
Use `pw.env.unset()` for env-scoped values you must clear.

When it happens

Trigger: Calling `pm.vault.unset('apiKey')` in any script. Always throws.

Common situations: Porting Postman scripts that clear/rotate secrets via `pm.vault.unset`. Cleanup logic that wipes a credential at the end of a run.
