Problem with deploy on Cloudflare

[Exqualibur]

Hello, I am trying to run a tool in Cloudflare. I have a paid plan. I follow the instructions, the instance starts up. However, when I enter the address of the page to scrape, I get the following error every time.

"Cannot read properties of undefined (reading 'get')",

Any suggestions? Thank you for any help.

Ensure the bindings are correct. I have noticed the setup script says npx wrangler kv:namespace create md_cache but the code looks for the name to be MD_CACHE, either change the code or the binding. I changed the binding, meaning i ran npx wrangler kv:namespace create MD_CACHE and added the change to my Wrangler.toml
