Also currently having this issue, want to point out too that when building with github it gives me this error:
A wrangler.toml file was found but it does not appear to be valid. Did you mean to use wrangler.toml to configure Pages? If so, then make sure the file is valid and contains the pages_build_output_dir property. Skipping file and continuing.

it errors out because it thinks its @cloudflare/next-on-pages when im using @openNextjs/cloudflare package. When I build locally like Richmond, this error disappears but instead I get the exact one he gets.
