### Context
When a valid governance action ID is provided, the outcomes details page successfully loads:
👉 [Example Valid URL](https://preview.gov.tools/outcomes/governance_actions/8d658da00803e3bddb49a0b85be24705bdea4317526b56ab651e5881b1cfc45f#0).

However, if an invalid or non-existent governance action ID is used, the page displays a blank screen and logs the error:
`TypeError: Cannot read properties of undefined (reading 'yes_votes')`

### Steps to Reproduce
1. Navigate to: [Invalid Governance Action ID](https://gov.tools/outcomes/governance_actions/56f39054758f1a3cedc1de9225d66bf270b62dfdbfbc5399f1d6d43aceffc63) (or any invalid governance action ID).

### Actual Behavior
- The page renders as a blank screen.
- The console logs the error: `Cannot read properties of undefined (reading 'yes_votes')`.


### Expected Behavior
- If the governance action ID is invalid or not found, the application should handle the response gracefully.
- Instead of a blank screen, display a message such as **"Governance action ID not found."**
