I am encountering the following error: `Error: This function should only be called through the recipe object`

```
  err: Error: This function should only be called through the recipe object

```

While trying to compose multiple overrides using a helper function (so code can be isolated).

This is the helper function I wrote:

```
const composeSuperTokensOverrides = (overrides: Array<ThirdPartEmailPasswordTypeInput['override'] | null>) => ({
  apis: (
    originalImplementation: ReturnType<
      Exclude<Exclude<ThirdPartEmailPasswordTypeInput['override'], undefined>['apis'], undefined>
    >,
    builder: OverrideableBuilder<ThirdPartyEmailPasswordNode.APIInterface> | undefined
  ) => {
    let impl = originalImplementation;
    for (const override of overrides) {
      if (typeof override?.apis === 'function') {
        impl = override.apis(impl, builder);
      }
    }
    return impl;
  },
  functions: (
    originalImplementation: ReturnType<
      Exclude<Exclude<ThirdPartEmailPasswordTypeInput['override'], undefined>['functions'], undefined>
    >
  ) => {
    let impl = originalImplementation;
    for (const override of overrides) {
      if (typeof override?.functions === 'function') {
        impl = override.functions(impl);
      }
    }
    return impl;
  },
});
```

And this is the actual usage:

```
override: composeSuperTokensOverrides([
  getEnsureUserOverrides(internalApi),
  env.auth.organizationOIDC ? getOIDCThirdPartyEmailPasswordNodeOverrides({ internalApi }) : null,
  /**
   * These overrides are only relevant for the legacy Auth0 -> SuperTokens migration (period).
   */
  env.auth.legacyAuth0 ? getAuth0Overrides(env.auth.legacyAuth0) : null,
]),
```

Any quick ideas?

We actually have an override builder that’s part of the override function signature that you should use

I think the issue may have been in the overrides you are composing in there, but I'm not sure

anyway, I think you should be able to compose overrides much more easily through the builder the override function gets

it has an override function that kind of emulates inheritance, otherwise you can run into binding issues exactly like the one you got

we don't, but: you can call `builder.override(overrideFunc)` where overrideFunc in your case is `override.functions` or `override.apis`
