just did - same issue

Thanks. Can you post your fly.toml? It looks like there’s an issue with the formatting of the TOML.

Ah, thanks for the toml tip. I couldn’t tell what was wrong (though maybe I had “services.concurrency” double-wrapped in brackets?), but regenerated the fly.toml and it deployed successfully - thanks!

Would be great to have some kind fly.toml validation and a clearer error message.

Thanks for the help!
