🐛 BUG: [ERROR] Transforming const to the configured target environment ("es5") is not supported yet

See original GitHub issue

What version of `Wrangler` are you using?

Unknown

What operating system are you using?

Cloudflare Pages

Describe the Bug

Started getting the below error in Cloudflare Pages today… (same code would build and deploy 2 days ago).

🚧 'wrangler pages <command>' is a beta command. Please report any issues to https://github.com/cloudflare/wrangler2/issues/new/choose
[ERROR] Transforming const to the configured target environment ("es5") is not supported yet

This seems like something that may block most Cloudflare Pages builds that are using functions.

@santsys , you’ve changed my mind. @0x8a 's approach of adding a tsconfig.json to the functions folder is the ‘correct’ way, so we’ll document that better. But if a tsconfig isn’t present, we’ll continue to look up as tsc and esbuild do today.

Sounds like we’re accidentally picking up a tsconfig.json that you have for your front-end code. Sorry about that!

I’ll file an internal issue to build Functions with our fixed TypeScript config.
