eachParent is not supported yet

Error message

eachParent is not supported yet

What it means

Deliberate unsupported-API error in the scripting environment's PropertyList: eachParent() mirrors Postman's SDK but Insomnia properties are not organized as a hierarchy, so calling it from a pre-request/after-response script always throws instead of iterating.

Solutions

1. Replace eachParent(...) in the script with iteration over the list, e.g. via each() or count()+indexing
2. Avoid relying on Postman-specific hierarchical property APIs in Insomnia scripts

When it happens

Trigger: Thrown at packages/insomnia-scripting-environment/src/objects/properties.ts:257 when the library encounters an invalid state.
