error: failed to select a version for `reqwest`.
    ... required by package `oghma-admin v0.1.0 (/tmp/renovate/repos/github/dnd-apps/oghma-bot/apps/oghma-admin)`
versions that meet the requirements `^0.12.4` are: 0.12.4

the package `oghma-admin` depends on `reqwest`, with features: `serde_json` but `reqwest` does not have these features.
 It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.
