[BUG] Assign shows BAD REQUEST pills for valid stat.ee POST

[matKlju]

Bug description:

The Assign element does not correctly parse and render response “pills” for a successful POST request to https://andmed.stat.ee/api/v1/en/stat/PA101.
Although a valid response is received (HTTP 200), the generated pills show “BAD REQUEST” in their hover tooltips instead of valid response paths.

Expected behavior:

• For a successful POST response, the Assign element should:
  • Parse the response body
  • Generate draggable pills for usable response fields/paths
• Pills must not indicate “BAD REQUEST” when the request succeeds.

Screenshots:
