Given flake:
```nix
{ description = "nix json error provenance";
inputs = {};
outputs = { self }: {
jsonFunction = _: "function";
json = builtins.toJSON (_: "function");
};
}
```
- Before:
```console
❯ nix eval --json .#jsonFunction
error: cannot convert a function to JSON
```
- After:
```console
❯ nix eval --json .#jsonFunction
error: cannot convert a function to JSON

3| outputs = { self }: {
4| jsonFunction = _: "function";
| ^
5| json = builtins.toJSON (_: "function");
