The error is clear: TypeError: Cannot read properties of null (reading 'name') in the /branches/page. This suggests something is trying to access the .name property of a null value. Let me check the branches page file:

I found the issue! The problem is on line 25:

When the page tries to render during the static build, branches is an empty array (it hasn't loaded yet), so selectedBranch becomes null. Then when it tries to access selectedBranch.name on line 203, it fails because null has no properties.

The issue is that this is a client component trying to use dynamic state during static generation. Let me also check the branches data file to understand the structure better:

Perfect. Now I understand the issue completely. The problem is that the page initializes with an empty branches array, making selectedBranch null. I need to fix this by ensuring selectedBranch always has a valid value during render. I'll add a null safety check and initialize with the default branches:

I've fixed the deployment error. The issue was that the page component was initializing with an empty branches array, causing selectedBranch to be null during static generation. When the component tried to render selectedBranch.name, it crashed trying to read the .name property of null.

I've fixed it by:

1. Initializing the branches state with defaultBranches instead of an empty array
2. Initializing selectedBranchId with the first branch's ID from defaultBranches
3. Adding a fallback to defaultBranches[0] in the selectedBranch calculation to ensure it always has a valid value

This ensures that the page always has valid branch data during both build time and runtime, while still allowing the API to update the branches after hydration.
