The FALLBACK_BODY_TOO_LARGE error indicates that the size of the fallback body exceeds the maximum cache limit. This error typically occurs in prerendered pages when the response body of a fallback page is larger than the cache can accommodate. Notably, if the fallback exceeds 10MB, it cannot be cached.
FALLBACK_BODY_TOO_LARGE:
Prerender fallback file is too big for cache
I'm encountering an error and reviewing the docs at /flg~eyJhbGciOiJIUzI1NiJ9._v7-_v39.f3M12-KAPZCzcefUX_oPWq-I0u4iAhoJCQaxpxor_bI/docs/errors/FALLBACK_BODY_TOO_LARGE to understand what's happening.
Please help me resolve this by:
1. **Suggest the fix**: Analyze my codebase context and propose what needs to be changed to resolve this error
2. **Explain the root cause**: Break down why this error occurred:
- What was the code actually doing vs. what it needed to do?
- What conditions triggered this specific error?
- What misconception or oversight led to this?
3. **Teach the concept**: Help me understand the underlying principle:
- Why does this error exist and what is it protecting me from?
- What's the correct mental model for this concept?
- How does this fit into the broader framework/language design?
4. **Show warning signs**: Help me recognize this pattern in the future:
- What should I look out for that might cause this again?
- Are there similar mistakes I might make in related scenarios?
- What code smells or patterns indicate this issue?
5. **Discuss alternatives**: Explain if there are different valid approaches and their trade-offs
My goal is to fix the immediate issue while building lasting understanding so I can avoid and resolve similar errors independently in the future.
To resolve this error, consider the following steps:
- Review response size: Examine the size of the response body for the affected page. If it's too large, try to reduce the content size
- Optimize content: Minimize HTML, CSS, and JavaScript on the fallback page Remove unnecessary assets or data to reduce the page size
- Implement pagination: If the large response body is due to extensive datasets, consider using pagination. This divides the data into smaller, manageable sections
- Dynamic data loading: Where possible, load data dynamically on the client-side instead of sending all data in the initial server response
To prevent this error, ensure that the size of the fallback page is less than 10 MB.
