== Invalid TOML definition

This error indicates that you have a syntax or grammar error in your TOML version catalog file.

This can happen if you use wrong keys, for example:

```toml
some-alias = { unknownKey = "foo" }
```

or that you forgot about some elements:

```toml
# missing the "group"
some-alias = { name="my-lib", version="1.0" }
```
