Getting error while deploying gatsby site in Cloudflare pages

I tried to deploy the gatsby site in Cloudflare pages and got the following error.
An unknown error occurred. Please try again later.
Kindly let me know any fix.

I can not see this error message anywhere in your posted screenshot. The error log is actually very specific and instructs you to make sure you are at least running Gatsby v2.24.78. Are you at v2.24.78 or newer?
Also it states it fails to load an image “/recurutiment1.jpg”. Does this image exist?

In general, does your Gatsby setup work locally?
