Blog post macro fails with "error: Failed to get macro details" when loading a lot of results

Issue Summary

Environment

any

Steps to Reproduce

1. Create a new page in a space that has at least ~300 blog posts
2. In that page, add a "Blog Posts" macro
   1. Ensure that "Content Type to Display" is set to "entire" (the default)
   2. Increase "Maximum Number of Blog Posts" to at least 300
3. Optionally, publish

Expected Results

Blog Posts macro should show results, at least partially with a "Load More" button.

Actual Results

• If the macro takes over a minute, it fails with "error: Failed to get macro details".
• If the macro takes less than a minute but more than 20 seconds, it fails with "Error: Rendering this content exceeded the timeout of 20 seconds."

Notes

Workaround

None really. If intending to search all blog posts on a single page, you can use the built-in search functionality.
