A 1102 error is a Cloudflare-specific error code for:
"The server exceeded a limitation set within Cloudflare."
A Cloudflare Worker exceeds a CPU time limit. CPU time is the time spent executing code (for example, loops, parsing JSON, etc). Time spent on network requests (fetching, responding) does not count towards CPU time.
Contact the developer of the “Cloudflare Workers” code to optimize code for a reduction in CPU usage in the active Workers scripts.
