hi @inland-taipen and in description add the issue number you solved |
What we did
Fixed two runtime crash bugs in the JSON Schema website:
Bug #1: Homepage crash when blogPosts is empty
Problem: Accessing blogPosts[0] without checking if the array was empty caused crashes.
Solution:
Added null/empty checks: const blogPosts = props.blogPosts || []
Introduced firstBlogPost variable with safe access
Wrapped blog post section in conditional rendering: {firstBlogPost && (...)}
Added fallback for reading time calculation
Bug #2: Homepage crash when calendar fetch fails
Problem: Calendar fetch errors left datesInfo as undefined, causing .map() to crash.
Solution:
Replaced .catch() that didn't return a value with a try-catch block
Defaulted datesInfo to empty array [] on error
Added TypeScript type annotations for datesInfo
Added safe array access: (props.datesInfo || []).map(...)
