what should I do?

[onekiloparsec]

The Poetry version provided by Render is < 1.2 (1.1.4 as of today). Which is problematic for anyone who has some recent Poetry config (like me).

A suggestion is to move to a deploy using Docker (not so happy of having to change all this just because of an old version of Poetry).

[punkyear2141]

Another way to resolve this issue is to use the older format for dev dependencies as described in the Poetry docs.

Specifically, change [tool.poetry.group.dev.dependencies] to [tool.poetry.dev-dependencies].

Note that the poetry.lock file won’t be compatible between poetry versions so you’d need to remove that from your VCS as well.
