# FALLBACK_BODY_TOO_LARGE

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.

## Troubleshoot

To resolve this error, consider the following steps:

1. **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
2. **Optimize content:** Minimize HTML, CSS, and JavaScript on the fallback page Remove unnecessary assets or data to reduce the page size
3. **Implement pagination:** If the large response body is due to extensive datasets, consider using pagination. This divides the data into smaller, manageable sections
4. **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.
