# Proposal not found

> No such edge proposal exists for the effective subject.

This page is the resolution target of the RFC 9457 `type` URI on every `proposal_not_found` problem body: `https://docs.get-exo.com/errors/proposal_not_found`.

**HTTP status: `404` Not Found**.

## Why it happens

Proposals belong to the subject whose graph produced them, and they are consumed when accepted or rejected. A proposal id that was already decided will not resolve a second time.

## How to fix it

* List current proposals with `GET /v1/proposals` under the same effective subject.
* If you already decided this proposal, the decision stands. Accepting an edge that now exists is not an error to fix.
